Is the yellowing caused by too much light and heat or is it just too much water.

It can be. If you have multiple lights that can be height-adjusted... Do a trial and error... Put one up higher... And leave one as is... Leave a seedling under the lower and see if the burn stays compared to the others under the higher light. if it's a single frame light...slant it. You'lll get your answer then. I know this isn't a straight answer but least you can deduce the possibilities with this process. If it's light the you know it's neuts! Good luck!

Also, it’s an autoflower, so you should be careful with the soil you start in, you don’t want too much nutes in there (too “hot” a soil). Autos usually need much less nutrients than reg photo period cannabis plants.

Maybe the soil is too hot? I guess you could be burning them with light if they were right up on the plant but it looks like you’re running a blurple LED and can’t imagine that is hurting it, and unless it’s scorching hot in there I wouldn’t think that’s the culprit either.

Single brighter/yellow leaves while floweringHi fellow growers,
Again I have to kindly ask for your help. She's in week 7 now, the 2nd week of flowering. I've noticed only the two largest leaves to shift towards a brighter green, almost yellowish. I'm hoping it's because of the flowering but I'm far from sure.
Thanks5y ago

Yellowing leaves.Is this a Nitrogen, Magnesium or Iron deficiency? I tried looking at pictures online, but they all look very similar. Or because of me under watering? I know I have not been giving them enough water. Growing outside in soil. Gave them nutrients 2nd of January.Leaves. Color - Yellow

Yellow tips on newer leaves. Nutrient burn or something else?I have noticed yellowing on the tips of newer leaves that seems to be slowly getting bigger. Nothing on older leaves. Start of Nutrient burn? I also have noticed some yellow/brown spotting on older leaves but that may be related to earlier PH flux that has since been fixed. TIA!Week 5

Mid flower flushHey guys :) Have you ever done mid-flower flushing and if yes, how did it work out? Gonna let the soil dry completely and then water nutes again. Could the pH being buffered to 7.10 (shit soil) be the reason for the yellowing leaves or does the plant need more or less of somethng5y ago

Yellowing on leaves tips. Should I start feeding her?Some yellowing appeared on the leaves this last day. Temps and humidity are controlled and ok. I haven't been feeding her, she has been growing on light mix for the past 25 days. Im thinking its time to start applying some nutes. Or could be something else? Thanks!2y ago
