Potentially overwatering. This post was awhile ago; has the plant recovered?
Looks like it is light burn with slight nutrient burn as well. If I read it correctly, these are autos and maybe don’t like such heavy amendments. Either way they look healthy enough to continue the fight 🌱🪴🤙🏻
Doesn't look like a big deal, if it gets worse I'd start to worry, maybe looking towards a nitrogen deficiency since it's the bottom growth(assuming it keeps working it's way upwards).Calcium and magnesium deficiency is also a possibility. it's just a few leaves and mainly old ones(when the stress happened). I could be wrong but besides your ph being a bit high, everything looks great.
What medium are you growing in?
What are you feeding them?
What's your watering regimen?
Possible beginning stages of light burn? I have the light set to 31 inches above the tops of them. I’m using a HLG 600rSpec and I have it set to 240 watts. I’m noticing the taller plants are actually all exhibiting a tiny bit of this symptom and the shorter ones not so much.
