Only single leaf, still cal/mag?

Walloomstarted grow question 6y ago

Anyone knows what causes a single leaf to show rust patterns, almost like cal/mag deficiency. Whole plant looks healthy except for this one leaf, literally. DWC, and I use tap water

It looks like light burned leaf. Second leaf looks like a little bit of Ca deficiency.

Ty @Yourgrowmie, I can definitely see it being light burn. She grew so fast and I haven’t adjusted light. It was at 16 inches and got light back to 24 inches. Hopefully, that was the issue.

help in Hydro RDWC/DWC Hello, my plants are now about 4 weeks old. The leaves droop and curl. The spots on the leaves are increasing. Is the PPM value too high? It's 1000ppm tds They grow in an RDWC system with top feed. The top feed is permanently switched on. Can that lead to problems?

Is this turning purple from temp change So it looks like what I thought was a brown spot (under the grow light), appears to be purple when I pulled it out to get a better look and stake it down. I did switch the light to something cooler, could this be from temp dropping. Not worried yet, just curious. Thanks

Foglie bruciate.Ciao ragazzi?spero vada tutto bene. Ho delle bruciature nelle foglie di una sola pianta, ho dato bio grow e top max biobizz. Umidità 50 % temperatura 27/30 °c purtroppo. Io penso sia dovuto alle luci troppo vicine, ma volevo un vostro parere. Grazie mille.

Is this a disease caused by a lack of calcium and magnesium?I pruned these problematic leaves during the flowering period, wondering whether this would lead to a decrease in yield. Calcium and magnesium were added every time I applied fertilizer. What caused the disease? Overnutrition burn?

Burnt? PH lock-out? too much Cal-mag??What do you think is wrong with this plant? All the other plants surrounding her are fine so I'm not sure what went wrong with this one. I thought it was cal-mag deficiency at first so I doubled cal-mag when feeding but it only proceeded to get worse. The buds look fine tho 👍😳

leaves dry and curling up Gelato canopy leaves continue to dry and canoeing up. I've backed off the lights, changed the air circulation, and gave only water in the last week, but the situation is just getting worse. Canopy buds are not growing and trichomes production is much higher in the lower branches
