Only single leaf, still cal/mag?

Walloomstarted grow question 6y ago

Anyone knows what causes a single leaf to show rust patterns, almost like cal/mag deficiency. Whole plant looks healthy except for this one leaf, literally. DWC, and I use tap water

It looks like light burned leaf. Second leaf looks like a little bit of Ca deficiency.

Ty @Yourgrowmie, I can definitely see it being light burn. She grew so fast and I haven’t adjusted light. It was at 16 inches and got light back to 24 inches. Hopefully, that was the issue.

Spots on leaves Anyone know what's causing this? Slight discoloration and rust spots, mainly on older leaves. It's not that bad but quite spread out. did spray with neem oil recently, so is it just burn spots or a nutrient problem?

Help diagnose hydroponic plants! Too much light/heat? Nutrient issue?The plant's leaves on the right are wilting and drying out, while the leaves on the left are spiking. Just did a nutrient/water change but it didn't help, and it looks like growth is being stunted on the right plant. Humidity has been around 45-55 rh and temp 70-80F
