horsemouthanswered grow question 6y ago
it could be a magnesium deficiency (especially the second picture). i looked your nutes and and dont know them, so if they contain magnesium forgot what i wrote.
under powerful leds, in my experience, plants need more magnesium and potassium than under hps or older leds.
cheers

Nitrogen Toxicity?Nitrogen toxicity? What does this look like to you? I gave a full set of nutes 3 days ago and it looks like the spots/yellowing are getting worse. I watered today with plain ro water ph 6.8 until runoff and tested it, ppm was over 900 ph was 6.2.

Outdoor northern lights auto yellowing earlyWith 3-4 weeks of flowering still to go, how worried should I be about rapid yellowing? I have kept feeding, i know she is rootbound and I havent checked pH. Do some plants just yellow earlier in flowering or should I act?

Yellow spots nute difficiency? Light burn?I noticed spots on both LB and NL that seem look like nute deficiency, my best guess is cal. I will check pH of soil runoff at next watering to eliminate lockout as a possibility. I've heard FFOF soil runs out in about 4 weeks, maybe that? Light burn from water drops on leaves?

Potassium deficiency?Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Papaya - looks thirsty and starts yellowing on lower half :'-(My very well trained photo Papaya (Nirvana - Citric x Ice) is significantly decreasing in happiness since yesterday. She looks thirsty but the fabric pot is still heavy and moist (watered 4 days ago), also the leaves on lower half turned yellow today. Too much / little of what?
