If you had leaves wet under light, possibly lightburn.

I'd guess a calcium and/or magnesium deficiency

Soft hanging yellow leaves, some with brown spots in the middle. Deficiency, Nutrient Burn or what could cause this ?Hey guys, I got a problem with two of my 4 plants. They started to develop yellow droopy and soft leaves that start to fall off on their own. I’m not sure if it’s a nutrient deficiency or blockout from ph or something else. I watered them only with water ph 6.5.

Why do my plants only have that light greenish yellowish look at the top and why is one of my plants also having those sick leaves at the bottom?2 of my 3 plants are a bit yellow-ish at the top since about a week. Plant 1 also had a couple of sick leaves at the bottom that I did remove. Those leaves had brown/dark spots, felt dry like paper, had very purple stems and did smell more like hay. More info in my report.

Too Much Light?Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flower The odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.
