IMPORTANT excess/deficiency? What's happening? Flowering is in danger
What's happening here? I think it could be Fe deficiency, Mn deficiency, S deficiency or maybe K excess. But I'm not sure about diagnostic and I think I can have more than one problem. Please help, I don't know how to solve it and I see how flowering is very slow and weak

Blotchy Leaves Problem - January 27 (Day 23)
In the last 24-hours all three of my plants have started to show signs of blotchy/irregular colored leaves. When I touch the blotches they are crisp to the touch. I have a really cheap pH meter, and I've been feeding at 6.5 pH. Is this a pH issue?

Strange spots in leaves, help PLEASE
Please, HELP. I don't know what's happening with these strange spots. Her growth is pretty good but I'm worried. Lights at 60cm. Nutrients, Temperature and RH are theoretically ok. I've even enriched it with worm humus a couple of times. Her sisters are really good all of them.

Some kind of deficiency?
World of Seeds Strawberry Blue. Pretty slow, uneventful life this far (on me). What seems to be wrong? Veg and a lot of light. FoxFarm soil. Half to full strength of the General Organics line.

Any ideas on this?
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? Advanced Nutrients 3 part. No supplements.

What's the issue with this leaf?
Can anyone help identify the issue on this leaf. Dreamcatcher is the strain and I can tell they were a reveg. It was root bound and I thought it was an issue with the roots. After transplant outside and sprayed with my IPM the plant has recovered but still has a few like this?

Healthy?
They are growing very fast right now, but some leaves have spots as you can see. Unfortunately, I watered with too high a pH value (around 8) in the first weeks, but I've adjusted that now and they are getting their 6.4. Maybe nutrient deficiency? Should I add Bio Grow?
