The leaves that appear to be pointing up are fine, but the leaves with discolored edges are a classic sign of potassium deficiency. The slight canoeing is probably just from a really warm day in the past few days, I wouldn't worry about that.

Nutrient issue or high heat?I believe I have an over nutrient issue or could this be due to high heat? My green house maxed out at 122 degrees, typically it reaches 105. The burnt tips showed up a day after the first nutrient feeding. Plus I have sheep manure and Iron earth in my soil. Did I over do it?

Leaves curling up after changing from HPS to MH I've had a question answered regarding leaf drooping due to overwatering/adding feed too early but now I've changed my bulb to a 600w MH the leaves are curling upwards. I've turned it down to 250w for now it's currently at 45cm above canopy level.Any ideas? Thank you ☮️

Why are there soon many brown spots all of a sudden in WK 7?I'm entering Wk 7 and the same lady is hurting again. She's been feeding heavy for last few weeks and doing great. So, I gave a light water/microbes dose w/can and Epson. Now I think its potassium or something else entirely... Brown spotting, yellow, crispy? Thoughts?

Twisted Leaves- is it genetics?This is my 2nd attempt at this plant. The 1st one germinated and died. I planted this one 8/10, popped 8/14 Again, it's struggling. Something funky is going on with the leaves. They are twisted and she's not thriving, especially in comparison to other tent mate. Is it genetic?

Is this "Tobacco Mosaic" on my Purple Lemonade Auto?First thought it was some water/light burns or a rust/leaf spot fungus. No other plants have it in the tent so not new light stress etc. Seems like it's a genetic and/or Tobacco Mosaic Disease/Virus? I'll finish the grow regardless but want to confirm it's not something worse

Leaf damage/discolouration The yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?
