Deficiency or environmental?
NobodysBudsanswered grow question 5 years ago
if any lower leaves have necrosis, Fe def
Zn def, since i didn't mention which before. starts at top, from in-to-out on leaf.
A slightly more acidic soil will help with both Fe and Zn without changing anything else, too.

Looks like zinc, but check pH first. that's more often a cause of trace element issues. If you use RO water, switch to tap. That may fix the problem with the trace elements too. (some exceptions for hard water > 300ppm)

Light burnI've got what I think is light burn. I can't dim or raise my LED lights (300w), but I'm currently running them 24/0. Would switching to 18/6 help? Or would it help to take the burned plant and have it out in natural light during the day? I'm growing autos and they're flowering.Week 11

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.
Thanks5 years ago

Yellowing and dry/brittle leavesHello all,
I've noticed the leaves are starting to yellow and some are getting quite dry/brittle. Is this a sign of overwatering or perhaps nitrogen deficiency?
It is on the same watering schedule as my other plant which looks healthy but obviously has different genetics.Week 10

Seedling yellow leaf ?A pair of second set leaves have sign of yellowness (it occurred a day before transplanting).
I'm not sure whether it is Nitrogen deficiency or any root problems?
(I will start adding more Veg nutrition which is rich in N this week)
Can yellow leaves turn back into green?Week 4

Lockout or deficiency?I have an issue with a girl.
Newbie alert.
I feel it’s either calcium def or nut lockout.
I fed with 1/2 rec BAC grow feed and it didn’t get better, so 2 days after I gave a flush of fresh water.
Now it’s really trying to grow, it’s kicking out new leaves but it’s stunted5 years ago

Help me get her better.Really need some advice on plant 3. She is now showing a lot of yellowing on bottom leaves. But now starting to move up to the top leaves. Can anyone help me get her better? Don’t like seeing her like this. I thought it was lockout at first but looks more like an N deficiency.5 years ago
