You are experiencing progressive potassium deficiency. Light nitrogen and heavy potassium are phosphorus in flowering. Good luck🌱

N or P deficiency?Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.

Leaf damage/discolourationThe 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?

Flushing don't seem to solve my lockoutIt's been 6 days since I noticed the problem. first thought it was a deficiency but really is a lockout.
I flushed 2 days ago but she keeps getting worse. Am I being impatient?
I flushed with tap water pH 6-7 until the runoff was in the same range and haven't fed her for 4 day.

Check out my week 7 update for more info. Only one plant in the tent affected so it's really bugging me?!? Thought it was overwatering. Left them 2 days between feeds and they are bone dry and pots are light. Any suggestions or could it just be a trait of the Pheno?Week 7
