Marijuana 20week garden tracker5/5/2023 Check the buds every day for any mold or yellow/brown leaves. It is not a nutrient deficiency, so keep feeding them. It may happen that the lower leaves begin to turn yellow and slowly die, but that’s normal. Now your buds go through their final growth spurt, but will primarily focus on compactness and THC production. You will see that the first hairs will color orange. You will notice that slowly but surely there will be a somewhat of a white deposit on the small leaves around the buds. Use a product like THC booster to provide the plant with optimal nutrition. The plant still needs nitrogen, phosphorus and other nutritious elements, but its most important requirement is now potassium. Your buds are now really starting to get some volume. This will help to stabilize the EC and pH levels of the plant and the soil again. Rinse your plants again at the end of the week with water not containing fertilizer, but do maintain a pH level of 6. The challenge is to optimally maintain the environmental conditions such as temperature, humidity and ventilation. This phase always takes long, and it doesn’t look like a lot of things are happening. Also check to see that your plants are not drying out. Make sure your fans stay on in order to provide the marijuana plants with fresh air. The buds continue to develop, and the plant will consume the maximum amount of water and CO2. Also red stems are a sign of stress and may indicate certain problems. Continue to feed them and pay extra attention to any damage to the leaves caused by insects or fertilizing problems. Insert a plant stick under a lamp and attach a thermometer to it to see how warm it really gets. The buds are even more sensitive to heat than the leaves. Make sure that there’s an optimal distance between the plant and the lamp, provide as much light as possible but don’t let it get too hot. The marijuana plant will no longer continue to grow and will only focus on the production of buds. Usually you can already switch after a week! Flowering Week by Week with Pictures You can switch to bloom if you notice that the tips of the plant leaves touch each other so you know for sure that you’ll get a nice sea of green. Aim a fan on its lowest setting just above the plants so it looks like they all ‘dance’ a little bit. And if you want to prune your plant, this is the right moment. You can add some extra nutrients, preferably with a high nitrogen product like grow booster. Also water your plants from below, this way the roots will search for the water and grow quickly in the bottom of the pot. Turn on all the lights and reduce the distance between the lamp and top of the marijuana plant to 1.6 ft (50cm), but make sure it doesn’t get too hot. You don’t have to add any fertilizer because it’s already present in the soil (hydro growers can start with EC 1.0). Spray your marijuana plants every day with a plant spray bottle to keep the humidity levels nice and high. Wait to water them again until the plants have used up all the water. Give your plants enough water for the first time so it flows out from the bottom of the pot. HPI light emits more white/blue light than HPS and this stimulates growth. If you have an HPI lamp, use it during the grow period. You want to let the marijuana plants get used to the light during the first week. Light Distance – 3.2 ft (100cm) between lamp and plant.Light Quantity – 50% of the lamps on (400watt HPI).
