Looks like there’s yellowing in between the veins of the leaf to me. That or the lights making it look that way. Anyhow that’d be magnesium deficien

I cant see the whole plant, but from the picture it looks like nitrogen deficiency.

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.Older leaves have brown/red rusty spots and looks like dying tissue in between the veins.
Burnt tips, and yellowing leaves.
The soil was really dry and my PH meter was 0.4 too high.
I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff.
Runoff was PH: 6.1 EC: 0.8

Strange yellow patchesThis is a new one for me, sont think I've ever seen discolouration like this before. My first thought was having left some nute solution on her leaves after feeding but pretty sure I've ruled that out and more leaves have begun to show the same discoloring. Any advice appreciated

Brown spots, PH in run-off is in the high end (6.5~)I see some brown spots on my leaves. I thought it was Calcium Deficiency caused by too low PH so I gave them PH 6.5~ with 30% run-off, and run-off shows at least the same PH so I think it is not too low PH, could it be caused by something else? Maybe too high PH or light-stress?

Blätter gelb und fallen ab Blütewoche 9I'm really worried about my plants right now, a lot of leaves are turning yellow really quickly and falling off on their own even though I'm fertilizing with every watering. Should I fertilize even more and water more often? The buds look good so far, but there are still more white hairs than flowers.

Leaf diagnosis: nutrient burn or deficiency (or both)?he leaves with the burnt tips appear to be more prominent at the top of the canopy, only affecting new leaves. A handful of these leaves look a little twisted. Meanwhile, the yellowing leaves are more prominent in the middle of the plant, just below the canopy

Strange leaves on seedlingHi everyone,
I started those two a day later than the others, the cotyledons grew normal but the first set of leave is quite strange.
The leaves don't grow opposite, but point on the same side... there are also some yellowish spot on them. I put a photo of the others to compare.

Yellowing leaves with brown spotsExperiencing some yellowing leaves with brown patching on this plant, I checked the plant doctor site and no deficiencies really matches the description 100% so it's left me scratching my head. What do you think it could be?
