MOcaverstarted grow question 5 years 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.

Brown Leaf Spots help!I have a serious problem with two of my girls and I can't figure out whats wrong.
The pics attached show the brown spots that have now spread to a good 60% of the leaves on each plant. I've defoliated as much of it as I can and its now affecting even the sugar leaves. Any ideas?

Do these random spots mean nutrient burn/deficiency, or is this normal?I have been feeding my plants 1/2 strength FF once weekly since week 3. The plants seem to be doing well. One has twisted leaves but seems healthy. But the plants are displaying random spots of yellowing. Is this normal or indicative of some kind of nute issue?

Is this a calcium issue?I noticed some discoloration on several leaves but not widespread. I think it is calcium deficiency but to make sure. Whatever ails her, a more informed opinion would ease my mind. Also, if it is a calcium issue, would raising from 3 to 5ml/gal of calmagic resolve it? (DWC)

Calcium deficiency?So, 2 out of 6 are showing this, it looks like a nutrient deficiency, Calcium I'd say.
It's only present in one leaf on each plant, in the bottom.
I've got here CalMag ready to apply, just wondering if you guys agree with me :D
Thank you, and keep it green :D

What could this be? Deficiency, or pests?White Crack in coco, currently late veg / pre-flower stage. Canna nutes being fed at EC 1.7 / pH 6.0 with runoff EC 1.3 / pH at 6.2. Noticed this on a single leaf this morning. Only change in last few days is that I am now filtering my water before mixing in nutes. Any thoughts?
