Any ideas on this?
MOcaverstarted grow question 6y ago
I'm guessing this is some sort of deficiency. Some of the spots are rust like and occur and young and old leaves. Any opinions?

I agree calcium deficiency is most likely the problem. Calmag will solve the problem.

Little browinish/beige dots near leaf veinsI noticed some weird little browinish/beige dots near the veins of some leaves, mostly the upper/center ones, those exposed to the light. I checked for bugs everywhere, even with the jewel loupe, and I haven't see one. What can it be? Maybe heat/light stress?

Discolouration on fan leavesGetting a white discolouration on my fan leaves. Thought it was residue from watering with nutrients as sometimes water will land on the leaves. But it doesn’t rub off, some parts look like it’s scratched into the leaf, some parts look almost bleached. But also considering PM?

See the last photo from Day 24.
There are a few spots on this one section of one leaf.
Because it's limited to this one area, I'm not too concerned.
But I would like to know if someone thinks this is a nutrient deficiency/excess or something to be concerned about.Week 4

Deficiency?I noticed this spot on one of the fan leaves. It only appeared in the last couple of days. I have been feeding small amounts of calmag and biobloom. I looked at deficiency charts but I’m unsure. What could it be?
