Undiagnosed leaf symptom

Hello guys,

I have DWC setup and growing amnesia haze, it s on flowering stage and a symptom appeared on the leaves that I could not diagnosed. Does anyone has experience and could say me what is it? As you can see on the photos, the forms of some leaves not good, they re curling asides.

I have kinda the same issue going on minus the curled leaves. That is a sign of pH imbalance and I would also check your phosphorus as well. The purple leave issue I don't know. Could be normal. Could be temp but I'm not 100% sure as I posted it as well before seeing yours

Thank you for answer bro but I am checking my ph and EC everyday twice. PH is between 5.9 - 6.1 and EC was 2.0 today, This issue must be something different. Maybe I am mixing the nutrients wrong I dont know or maybe the phosphorus issue as you say. That symptom mostly looks like phosporus but that curling leaves I have never seen before. I hope somebody will diagnose and give me troubleshooting about this

I think your issue is nutrient burn or zinc deficiency. That started from the tips. Check your EC and that should be max 2.2 but just in case I always keep it between 1.8 - 2.0. And puple leaves sometimes because of the genetics, sometimes the drop of the heat. I havent see any issue about purple leaves yet.
