Overall all your plant looks fine , might be the beginning sign of nitrogen toxicity, Dark green leaves, shiny leaves, clawing, weak stems, and overall slow growth. Marijuana leaves that are nitrogen toxic often get “The Claw” or talon-like leaves that are bent at the ends. They also do an odd curving (or cupping) that is often mistaken for overwatering, but is unique to nitrogen toxicity. just back off a bit with the nitrogen for a few feeds and you should be good . Hope that helps and good luck to you

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?

Nitrogen Toxicity? (Day 20, autoflower, Biobizz All Mix soil, only used CalMag and no other nutrients) My other plants look fine.Is this Nitrogen toxicity? My temps are 20-24°C, RH 60-70%, DLI ~20 and they are not overwatered. Brreder says this strain is also sensitive to Nitrogen. Is Biobizz Allmix soil just too hot for this plant. Anything I can do besides hoping it powers through until it is bigger?

They’re in coco, 3-gal pots, 480W QB at 50cm, 2.2 EC daily, no pH check. Problems started after adjusting watering for larger plants. Any tips?

This margin curl appears to have spread from one plant to 2 of the other 3. So I assumed not pH, not lockout, not nutrient based. Roots all great. I've culled the 3 and there is 1 survivor doing well but what was this? In the diary I mention using Temprid FX, Neem, Spinosad.

Maybe PH Lockout?Hello everyone, can you maybe help me? My Black Cherry Punch has some kind of problem. I suspect it’s a nutrient lockout caused by the pH value. I flushed it two days ago, and the drain had a PPM of 1000 and a pH of 7. The plants are at the beginning of the 2nd week of flowering.
