Rusty brown spots on edges of leaves near top of the canopy
MediciGradestarted grow question 4y ago
I'm not sure if this is nutrient burn or a cal/mag issue (deficiency or lockout), or something else. Anybody know what is likely to be causing this, and how to treat it?

I don't think it's a cal mag problem. It could be due to using up the potassium. I would be tempted to leave your nutes as is but increase the bloom slightly and see how that goes.

Brown spotting?Hey everyone!
My plant is in her 5th week and a few days ago (around day 30) I noticed some brown spotting on a few of the mid/lower leaves. Does anyone know what this could mean?
I gave her her first feeding 3 days ago. 1/4 strength veg nutes and 1/8 strength bloom nutes.

Yellow tipsI noticed the tips of the leaves starting to yellow, mainly on the new growth.I haven’t noticed any other issues, being my first grow maybe I’m overlooking something. I raised my light up to 26-27 inches from 18 to see if that helps. Could this issue be from something else?

Yellowing, burnt tips and edgesHello fellow growers I noticed this happening rapidly after I top dressed. What kind of deficiency is this? Is this nutrient burn as well as a deficiency? Solely a Ph problem?. So far I’ve come up with maybe potassium deficiency and improper Ph when watering? Please help

Burned tips and holes in leavesHello! Hoping to get some insight into why the leaves on this girl have holes and the tips are breaking off. Thinking maybe nutrient burn? I’m using slow release nutes from Gaia Green. I used premixed coco I had already amended with 3 tbs/ g of 4-8-4 and 1 tbs/g 2-8-4 top dressed

Nute burn or pH FluxIve noticed the tips are the faintest of yellow. Maybe ive mistaken Nute Burn for pH Fluctuations?
Diagnosing: pHing both tank and run off showed different ranges. My CYCO Coco pre-mix was ph buffered. The De-Gnat agent that goes over the coco for mite protection maybe causing.4y ago

Deficiency or excessHello colleagues,please advise me, what could it be? the tips of the leaves are sometimes lighter, and the holey leaves? I didn't find any pests in the tent. I use the AH set. Once a week I only rinse with water with enzymes. Can you think of anything?

Brown spots watering in coco multiple times a daySeeing brown spots on the leaves. Assuming it's a calcium deficiency. Added another ml/gal of Cal-Mag for the daily feeding. Besides that, what else could it be? Also, at what point do you water plants in coco twice a day?
