Leaves looking f’d?

GardeningDougstarted grow question 6y ago

What’s happening with these leaves? It started last week and has spread. Only the leaves in the middle under the light. Week five of flower. Was using the same nutes and strengths since flowering started at 6ph. Upped the strength this week to see if it would fix and it got worse

Could be light burn from ur grow light being only 8 inches away. I know its lower watt but still 8 inches seems rather close to me. I'd back the light off to like 12 inches. Make sure to check ur mediums ph after u water with 6ph solution. Ur ph could be off causing ur necrosis. Happy growing and stay lit fam.

Looks to be calcium deficiency, or light / heat stress. Looking at your diary 8in away from canopy might just be light burn . Back your light off just a bit or add more air flow to the top of canopy.

I believe I have a phosphorus deficiency from lack of watering/early pH issues. I also have curly/dented leaves that can be seen in the close ups. Does this seem like a phosphorus deficiency or what else may it be?

Cal-Mag and N Deficiency in Flower? Thanks!I'm guessing the yellowing and brown spots (in Wk 8 pics) are related to Cal/Mag and maybe a lack of N? Would love some advice from someone who's seen this before Thanks! I'm seeing this in all my grows to some degree- using FF trio and FFOF but not for much longer
