Your plants were stretching, setting bud sites, and getting ready for the main event. Now, in week 4, the show is starting. The initial “stretch” has likely stopped, and your plant is focusing all its energy downward—into the flowers. During this phase, you’ll notice a few key changes:Buds Are Swelling: Those small, wispy buds are now becoming more substantial. They are stacking on top of each other, forming more recognizable flower structures. Aroma Increases: You may start to notice a more pronounced fragrance as the plant’s essential oil production ramps up. This is a great sign of healthy development! Energy is Focused: Your plant is no longer concerned with growing taller or making new leaves. Its entire biological focus is on reproduction, which means creating the biggest, most viable flowers possible.Understanding this energy shift is the key to providing proper care. Your job as the gardener is to facilitate this process, giving the plant everything it needs to perform at its absolute best. This is where our week 4 flowering tips come into play. Your Essential Week 4 Flowering Care Guide: Nailing the Environment Your plants are incredibly sensitive during the mid-flowering stage. Creating a stable and optimized environment is one of the most impactful things you can do. Let’s break down the three pillars of environmental control. Light: The Fuel for Flower Production Light is the engine that drives photosynthesis, and during flowering, your plants are hungrier for it than ever. Ensure your grow lights are positioned at the correct distance—close enough to provide powerful energy but not so close that they cause light burn on the top leaves. For most flowering plants, a consistent light cycle is non-negotiable. If you’re growing indoors, a strict 12 hours on, 12 hours off schedule is the standard. Any interruption during the dark period can stress the plant and potentially hinder flower development. A simple outlet timer is your best friend here. Temperature: The Comfort Zone Think of temperature like a comfort setting. If it’s too hot or too cold, your plants will be stressed and won’t perform well. In week 4, aim for a daytime temperature of around 70-80°F (21-26°C). At night, a slight temperature drop is natural and beneficial. A drop of about 10-15°F (5-8°C) mimics natural conditions and can even help promote vibrant colors in some plant varieties. Avoid drastic temperature swings, as this can shock your plants. Humidity: Finding the Right Balance Humidity is a major factor in preventing mold and mildew, which can ruin an entire crop. As your flowers become denser, they trap more moisture, creating a breeding ground for pathogens. In week 4, you should aim for a relative humidity (RH) level between 40% and 50%. If your humidity is too high, use a dehumidifier or increase air circulation with oscillating fans. Good airflow not only helps control humidity but also strengthens stems and helps your plants “breathe.” Feeding Your Flowers: Nutrient Best Practices for Week 4 As your plant’s focus shifts, so do its dietary needs. The “how to week 4 flowering” puzzle is solved largely by understanding nutrients. Gone are the days of high-nitrogen vegetative fertilizers. It’s all about phosphorus and potassium now. The Power of Phosphorus (P) and Potassium (K) These two macronutrients are the superstars of the flowering stage. Here’s what they do:Phosphorus (P): Crucial for energy transfer and the development of dense, heavy flowers. Potassium (K): Helps with metabolism, water uptake, and activating enzymes that are essential for producing sugars and starches—the building blocks of your blooms.Look for a high-quality “bloom” fertilizer specifically formulated with lower nitrogen (N) and higher levels of P and K. At this stage, you’re likely at or near the peak feeding strength recommended by the manufacturer. Always read the label and start with a slightly lower dose to avoid nutrient burn. Don’t Forget the Micronutrients While P and K get the spotlight, don’t forget about micronutrients like Calcium (Ca) and Magnesium (Mg). These are vital for cell structure and photosynthesis. Many growers supplement with a Cal-Mag product during flowering to prevent common deficiencies, which often appear as yellowing leaves or brown spots. A Sustainable Week 4 Flowering Approach For those interested in eco-friendly week 4 flowering, you have wonderful options! Top-dressing with high-phosphorus bat guano or worm castings can provide a slow-release source of organic nutrients. Brewing a compost tea with these amendments can also give your plants a fantastic microbial boost, improving nutrient uptake naturally. Watering Wisdom: How to Quench Your Thirsty Plants Watering seems simple, but getting it right is an art. Overwatering is one of the most common mistakes gardeners make, and it can lead to root rot and other serious issues. During week 4, your plants are likely very thirsty as they power flower production. However, you should always check the soil before watering. Don’t just stick to a rigid schedule. The best method is to feel the soil. Stick your finger an inch or two deep. If it feels dry, it’s time to water. Another great technique is the “pot lift” method. Get a feel for how heavy your pot is right after a thorough watering. Then, periodically lift it. When it feels significantly lighter, it’s ready for another drink. When you do water, do so thoroughly until you see about 10-20% runoff from the bottom of the pot. This ensures the entire root zone is saturated and helps flush out any excess nutrient salts that may have built up. Common Problems with Week 4 Flowering (And How to Fix Them) Even with the best care, you might run into a few bumps in the road. Don’t worry! Spotting issues early is the key. Here are some common problems with week 4 flowering and how to address them. Yellowing Leaves (Chlorosis) A few yellowing leaves at the very bottom of the plant are normal; the plant is simply redirecting energy from them to the flowers. However, if you see widespread yellowing moving up the plant, it’s a sign of a problem.Nitrogen Deficiency: If the yellowing starts at the bottom and moves up, it could be a lack of nitrogen. While you lower N in flower, you don’t eliminate it entirely. A small boost might be needed. Magnesium Deficiency: Yellowing between the veins of the leaves (interveinal chlorosis) often points to a magnesium issue. This is where a Cal-Mag supplement comes in handy. pH Imbalance: If the pH of your soil or water is off, the plant can’t absorb nutrients, even if they’re present. Check your pH and adjust it to the 6.0-7.0 range for soil (5.5-6.5 for hydro).Burnt Leaf Tips Crispy, brown, or burnt-looking leaf tips are the classic sign of nutrient burn. This means you’ve been a little too generous with the fertilizer. The solution is simple: flush your soil with plain, pH-balanced water and reduce the strength of your nutrient solution in subsequent feedings. Pest Patrol Denser foliage and flowers can be an inviting home for pests like spider mites and aphids. Inspect your plants regularly, especially the undersides of leaves. If you spot pests, act quickly. For a more eco-friendly week 4 flowering pest solution, consider introducing beneficial insects like ladybugs or using a gentle, plant-safe insecticidal soap. Avoid harsh chemical pesticides that can harm your flowers. Pro-Level Week 4 Flowering Tips for an Abundant Harvest Ready to take your garden to the next level? These advanced but easy-to-implement tips can make a noticeable difference in your final results. Provide Physical Support As your flowers get heavier, they can put a lot of strain on the branches. Some may even bend or break under the weight. Use bamboo stakes, yo-yos, or a trellis net to provide support. This ensures the plant can dedicate its energy to fattening the buds, not just holding them up. Consider Light Defoliation This is an advanced technique and should be done with care. Defoliation is the process of selectively removing a few large fan leaves that are blocking light from reaching lower bud sites. By allowing more light to penetrate the canopy, you can encourage the lower flowers to develop more fully. The key here is less is more. Only remove a handful of leaves at a time. Never strip a plant bare, as the leaves are its solar panels. The goal is to improve light exposure, not to stress the plant. Frequently Asked Questions About Week 4 Flowering

Frequently Asked Questions About Week 4 Flowering
Should I still be pruning in week 4 of flowering?
Major pruning should be complete by now. Your plant needs its energy for the flowers. The only exception is light defoliation, as mentioned above, or removing any clearly dead or yellowing leaves at the bottom of the plant. Avoid any high-stress training or topping at this stage.
What do yellowing leaves mean at this stage?
It depends on where they are. A few yellow leaves at the very bottom are usually normal as the plant cannibalizes them for mobile nutrients. If the yellowing is widespread, in the middle or top of the plant, or has patterns, it likely indicates a nutrient deficiency (like magnesium or nitrogen) or a pH issue. This is one of the most common problems with week 4 flowering, so observe carefully.
How can I make my flowers more fragrant and potent?
Aroma and potency are largely determined by genetics, but you can help your plants reach their full potential. Providing the right “bloom” nutrients, maintaining an optimal environment (especially temperature), and ensuring strong light are the best ways. Some growers use organic supplements like molasses or terpene enhancers in the final weeks, but a healthy plant is the number one priority.
Your Garden is on the Home Stretch!
You’ve made it to the midpoint! Week 4 of flowering is an incredibly rewarding time where you get to see the real results of your hard work begin to take shape. By focusing on a stable environment, providing the right flower-fueling nutrients, and keeping a watchful eye for any potential problems, you are setting the stage for a spectacular finish.
Remember, gardening is a journey of learning and observation. Every plant teaches you something new. Trust your instincts, follow these week 4 flowering best practices, and get ready to enjoy the beautiful, bountiful harvest you deserve.

Ready to take your garden to the next level? These advanced but easy-to-implement tips can make a noticeable difference in your final results.
Provide Physical Support
As your flowers get heavier, they can put a lot of strain on the branches. Some may even bend or break under the weight. Use bamboo stakes, yo-yos, or a trellis net to provide support. This ensures the plant can dedicate its energy to fattening the buds, not just holding them up.
Consider Light Defoliation
This is an advanced technique and should be done with care. Defoliation is the process of selectively removing a few large fan leaves that are blocking light from reaching lower bud sites. By allowing more light to penetrate the canopy, you can encourage the lower flowers to develop more fully.
The key here is less is more. Only remove a handful of leaves at a time. Never strip a plant bare, as the leaves are its solar panels. The goal is to improve light exposure, not to stress the plant.
Frequently Asked Questions About Week 4 Flowering
Should I still be pruning in week 4 of flowering?
Major pruning should be complete by now. Your plant needs its energy for the flowers. The only exception is light defoliation, as mentioned above, or removing any clearly dead or yellowing leaves at the bottom of the plant. Avoid any high-stress training or topping at this stage.
What do yellowing leaves mean at this stage?
It depends on where they are. A few yellow leaves at the very bottom are usually normal as the plant cannibalizes them for mobile nutrients. If the yellowing is widespread, in the middle or top of the plant, or has patterns, it likely indicates a nutrient deficiency (like magnesium or nitrogen) or a pH issue. This is one of the most common problems with week 4 flowering, so observe carefully.
How can I make my flowers more fragrant and potent?
Aroma and potency are largely determined by genetics, but you can help your plants reach their full potential. Providing the right “bloom” nutrients, maintaining an optimal environment (especially temperature), and ensuring strong light are the best ways. Some growers use organic supplements like molasses or terpene enhancers in the final weeks, but a healthy plant is the number one priority.
