Yellowing, wilting, stunted growthCan anyone please help me identify whats wrong with them. I've done a flush, adjusted the lights, reduced the nutrient strength, I've pretty much done everything and still stunted growth and they are still looking weak and frail.

Yellowing on older fan leafHey guys, my photo sour d has some earlier growth showing some yellowing in the center of a few leaves. I fed this plant a foliar spray of cal mag plus way back in the 2nd or 3rd week and it got burned on the leaves but does this look more like a deficiency?Week 5

Should I cut the dried leaves at the bottom?Should I remove the dried leaf in the bottom? I was thinking that it might redirect unnecessary energy to the plant since the leaf might be too far gone to save. I was thinking of starting topping next week as well, when the fifth node start to show more.5y ago

Overfeeding?Is this the first sign of nutrients burn? Some tips of the leaves are turning yellowish and two leaves are starting to make dark dots...maybe too much nitrogen? š¤The temperatures in my grow box are a little bit low, but I don't think it's the case. The ph is regular.3y ago

Name the deficiency.Problem is mainly occurring on leaves near the top, but not the newest growth. Initially are less green, then start to yellow followed with brown spots. The oldest leaves near the bottom are seeing some effects, but as acute as the mid-upper leaves. Curl likely due to warm tempWeek 4

What do you think the problem could be?Thereās something going on with some of these plants and I canāt seem to identify the problem so far. I have been doing a lot of research and Iām in a process of elimination at the moment but the plants growth hasnāt been affected. I will continue to try treat the problem.Week 5

Maybe nutrient burn or?My biggest plant has started looking a little sick, have a feeling it may be some type of nitrogen toxicity? Maybe itās just got some nute burn? I have flushed it out and will leave it be for a few days and hopefully it perks back upWeek 4
