[GreenMedicalPatients]

Anybody know what nutrient this plant is deficient in? The markings start at the top and are the worst under direct light. Feeding with jacks 321 in coco.

Are you adding Epsom to your water?

Yeah, and cal mag too sometimes. Does it look like mag to you? Thats what i thought originally but now im second guessing myself because it starts on the top of the plant and I read that mag is mobile.

When I switched to LEDs I upped my mag a bit. Magnesium deficiency I believe starts showing at the top. I’d add 1tsp per gallon and I think it will fix your problem.

Looks like mag def. You can spray the undersides of the leaves with mag just before lights out. People suggest a tsp or tbls per gallon in distilled or RO.

only on my second grow, but I use these to get my best guess and then also ask here. Based on the second chart/pic, Magnesium?
