Any idea what is causing this crisping on a few of my leaves? I am maybe seeing some slight curling/taco-ing on the upper leaves too?
I think the PH might be a bit high in my water too, it's 7. I've ordered a filter and some PH Dwon, the PPM was only 250. Related?

Clawing/Yellowing? (def not over watering)Anyone want to take a guess at what's going on with the clawing/yellowing? Very highly doubt it's over watering. It's slowly been showing more signs of it the less I water and I'm pretty heavy on perlite. Also using the lower recommended amount on the nutes.Leaves. Curl up

Two part leaf question.Two parter 😁.
Are the new leaves on my plant deformed or am I being paranoid?
How can I stop leaf curl? At first I thought it was a light/heat issue but both light and temps are fine and it doesn't feel too humid in there.

Getting out of the ideas - VPD, nutrients or deficiency?I'm getting out of the ideas as the foliar symptoms proceed.
Lowered EC down to 1.8 from 2.2, pH in range.
VPD is getting problematic as the plants seem to be respirating a lot during the day and it rises tent RH sometimes up to 70% - exhaust duct fan wont keep up. Temps 22-24CLeaves. Edges burnt

Yellow tips upper/newer growthI'm experiencing some yellowing of the tips in the upper/newer growth. Light stress? Nutrient burn? Deficiency? Ph related issue?

Something bad is going on with my Hulkberry plant. I think it might be due to giving it to much fertilizer.
