Nutes over/under?

This is from the rapid growth during flowering. During the first 3 weeks there is rapid growth which will result in a much greener site. I'm not seeing signs of deficiency or burning. Remember they stretch 2-3 times in flower. Nothing I personally would be worried about friend. The "cupping" of the leaves is most likely from heat / light stress.. Mist them down with water every morning before lights or sun up.. when it's below 80f and the stoma are still open. this will help combat this issue next time! Happy growing! 👊
