Potential heat stress
Adam1420started grow question 4y ago
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.

Nutrient lockout? [first grow]My plant’s started showing signs of nutrient burn, so I have flushed them with just water, after 1 day they turned to worse condition than before.
Is it nutrient lockout? Or just deficient?
Appreciate every feedback!

Yellow leaves working out towards tipsYellowing of lower leaves, from the stem working towards the tips. It’s been hot and they’ve been home alone for 5 days with just one water on the 3rd day. They had a small amount of bloom just before I left! During veg they were on fish mix, but not very much (1/2 dose).

Defficiency? 1st growI’m unsure of what is wrong with my plants. Leaves are turning yellowish colour and withering, first affecting old growth in week2F autoflower genetics.

Early senescence on Runtz?Based on your experience growing Runtz and/or the pictures posted below, what week would you say we're in? I'm asking cause leaves are yellowing and unless I overwatered them it looks like a very early senescence, no?
I'm a newbie so there are obvious things I don't see :)
