Stick answered grow question 3 years ago Hi @PapaSmurf416! Nitrogen plays an important role in your plant's health: this type of yellowing usually means that your plant is not able to find enough Nitrogen. Too much Nitrogen = dark leaves, stunted flowers, big stretch. Not enough Nitrogen = yellow leaves, lack of vertical stretch, bottom leaves dying. Your slight Nitrogen deficiency is related to the plant doing its "stretch" cycle. Once your plant enters into flowering stage, she focuses on vertical stretching for a few days, before putting all its energy into bud expanding and resin production later. In your situation, I won't worry that much, the stretch should be over now and your plant is going to need less N and more P+K. What's your soil and what's your feeding schedule? Depending on those elements, you will probably need to add some P+K into your next waterings, to help flowers to expand. Hope this will help, keep us updated and happy growing! :facepunch:
Don't a lot of people when germinating or cloning add in a very mild bloom nutrient? Maybe if you gave them a super mild dose of a PK the purple stems may go away and if not then you are probably right about the genes...
I think perhaps I’ve been overwatering the smaller guys and suffocating them a bit. Also one of the VK has some severe droopyness and burning tips. Will update in 2 days on all. Thank you! I just put in some extra holes in the sides of all the cups. :crossed_fingers:
@PapaSmurf416, I think the light may have been too close then. With Leds you have to be really careful to judge the correct height, as they start growing more leaves or if you notice them Stretch, bring the light a little closer and monitor it until you find the sweet spot! Looking good though!
@Fruitgrower, Hey at maximum power they produce I think 320 or 340 watts but I’ve only had it less than half power so probably 140. They are Samsung lm561 c strips. I think temps in the tent have been to hot for a while. I raised the light to 34 inches
@PapaSmurf416, could be the light is too hot or too close. What power do the led produce?
