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.

Hi growdiaries,
Got a couple of issues on my plants here. The last 4 pictures show the problems, firstly there are holes appearing in the leaves and it looks like something is eating them. Haven't seen anything alive. Also a few spots appearing. Mould? Had bad air for a bit.Week 5

Hello, I just noticed that some of my leaves are starting to have slight discoloration and some holes. See images in week 6. I don't see evidence of bugs or mildew and my fan may have been too close for the leaf with holes. I feed once a week and have switched to a high K feed.Week 6

Does this look like minor leaf burn, too many nutrients or something else?I believe two of the plants developed minor leaf burn. One has white streaks on the middle and outer portions of several leaves, and the other has a rust, reddish stripe parallel to the center of several leaves. I’ve attached pictures above. Thoughts are greatly appreciated.5y ago
