Leaves yellow and spotted
willertexstarted grow question 4y ago
Can you please figure out what is going on with the plants in the pictures? I'm using RO water with AN and I already added calmag (1ml/L), grow a-b and B52
The first plant is more involved in the problem, the second one started to show symptoms few days ago. EC=1 pH=6. Thx 🙏

I just thought about sulfur deficiency... but it could also be a fungus - look up "Septoria." I would isolate the affected plant from the rest for now.

Massive series of problem, might be killing herThis plant is giving me a hell of a job :( I'm trying to fix problems each watering but it seems that I present new ones when I do so, I'm feeding about 2.5l each time ph around 6-6.5 and I've tested runoff coming at 6.5. What are this series of problems?

Yellow/burned tips & curled leavesI have an issue with some yellow/burned tips and curled leaves.
I already suspect that mainly is from light stress but could also be a nutrient deficiency?
I´ve raised the lights the max I can and keep it at 80% for 20 hours.
