If you had leaves wet under light, possibly lightburn.

I'd guess a calcium and/or magnesium deficiency

End of Cicle or High stress???
Good morning everyone! First, thanks for the replies to my last question. 2 of my 3 girls are doing much better, but sadly one is still very stressed. As a beginner, I’m not sure if it’s normal end-of-cycle or if she’s still suffering. Thanks, Jack

Brown roots : Is this Pythium?
Is it chlorosis, deficiencies, septoria, pythium ? calmag, iron, H2o2 or mycorrhizae needed ? What would you do to save the crop (preflowering stage) ? Thanks a lot for your help

I need help troubleshooting weak plants! I think the clover might be the culprit but what do I do?
Can anyone tell me what’s going on with these plants and what I can do? This is my first grow. I can already tell the seeds are growing slow because other seeds I planted in smaller pots are growing much faster. Any advice would be greatly appreciated!

Leaf discolouration. Nutrient deficiency?
Leaves are discoloured and clawed. Started about a week ago with yellowing of tips and clawing at top of the plants. Now lots of leaves are slowly changing colour. Thought it was nitrogen toxicity but my runoff is 330ppm. Are they deficient in nutrients?

Light or nutrient burn?
Ive been having yellow tips on the tops of both my plants for some time now, I already raised the light up a bit higher than the maximum height the manufacturer recommends, but Im still having the yellow tops. Could this be nutrient instead of light burn?

Yellowing leaves on bottom and middle
I am growing in organic soil and transplanted 3.5 weeks ago from .75 gallon pot to 2.5 gallon pot. I noticed some yellowing on some of the leaves, generally towards the bottom but a little in the middle. Is this a cause for concern or do some leaves natural die off?

overnight yellow leaves with brown spots
These leaves (about halfway up on #1) turned yellow with brown spots overnight. I didn't check the soil before giving it nutrients two nights ago so I was wondering if it has to do with overfeeding. The soil is damp and kinda packed together. Any idea what's going on?

Yellowing Leaves, Red Stems, Brown patches.
pH is correct - run off ph, too. These are 2 out of 4 plants who show these signs. I gave less Flowering Nut in fear of giving too much Nitrogen. Cal/Mag is in use. Is it Phosphorus/Potassium def? I just flushed and gave BioFlores in recommended dosage again. Thoughts?

End of Flower, Yellow and crusty leaves ok ?
Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves. Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?
