Sheet! Good news is they are green! Your qb draws 240 watts. 240 watts for a for a 2x4 tent def is not over doing it. Wow, I cannot imagine it’s all that? I’ve really only used cheap purple LED lights before 350 watts they were. I’m sorry. I should have considered it more and Gave you the same advice as Rurumo did. What can happen in situations where the light is ramped too quick is the increase in light and to some extent heat can cause a spike in water/ nutrient uptake that can “shock” or stress the plant out somewhat giving them the downward leaf curl like they look at lights out. They are trying to restrict transpiration. This seems likely. I’ve seen this type of stress but under more extreme conditions. On occasion Plants coming out of a 65-70 degree veg room from under t-5’s, then potted up and placed Into the flower room lit with 1000 watt hps lamps and these plants showed the exact same downward leaf curl symptoms as yours. Much, much worse if they were on a heavy feed schedule before the transition. I dimmed the lights to 600 watts and gave them water only no nutes, then ramped everything up gradually over the following week. They came back just fine and I am fully confident yours will as well.
What Rurumo stated in that last post about gradually increasing the light to 100%. That most likely would have lessened the shock. Your plants were on a slow but steady track and a gradual increase would have followed suit.
So your at 80% and the light is one foot higher than it was when it was at 60%? That sounds good. The intensity should be close to where it used to be. I cannot see that adding any more stress at this point. Make sure they are hydrated. I’d go w quarter strength nutes if any for a few waterings or until plants start to look normal again. If you have been feeding regularly they def not going to miss nutes for a few watering. Then go back to 100% and GRADUALLY lower your qb to your desired height. I’m sorry I’m so long winded. Just make sure no other stressors like lack of water or high temps mix in is all.
Something I just thought of.,, they aren’t pot bound right? Long as the root ball isn’t rock hard. If it is that adds another layer to all this and probably another long ass fucking novel from the genius who told you to go from 60-100% in one day. I Honestly would never have thought! Doesn’t matter how long I’ve been growing! I still learn every day and make plenty of mistakes trying to interpret plant to English. Lol I guess? Ya gotta keep me posted. Please!
