What is going on with these leaves?
IndigenousOrganicsstarted grow question 4 years ago
Tips of top leaves slightly brown, no curling. We had some hot days where humidity was kept low, but heat from dehumidifier plus outside temps got up to 91f. Some leaves at top have strange marks a bit concerned. Living soil, Marphyll, bat guano, molasses only.

Btw just a tip, if you have a higher temperature allow the humidity to stay higher so she can still transpire at a proper rate, higher temps higher humidity, lower temps lower humidity.
That could also be a potassium excess wich in turn can cause zinc, iron, calcium and magnesium deficiencies.
Check for signs of new foliage developing thinner blades or interveinal chlorosis in newer leaves.
Best of luck growmie and stay lit.

You may have toxic soil, looks like they are getting too much N. It's also possible, you have calmag deficiencies on top of that.

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)

Burning tipsHi, I notice the some burning on the tips, I think it is related to nitrogen toxicity, it started happening during early flowering, I have been adding cal/mag & b52 and they also contains more nitrogen. I have been topping just plain water for the last week.Anyone had this issue?

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?

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?
