Wizard - Pheno Hunt 1

In my experience the first few leaves on some strains just do that. I wouldn't worry about it, just keep things where they should be and new growth will be normal.👊

Possibly the cause, I believe you have a root issue though. Try adding some enhancer to your soil. Something with humic acids to help break down unhealthy roots to proper growth can resume. The plant behind it is showing signs of heat and light stress so your environment may be too dry causing the same issue. Always water with pH 6-7 in soil. Add CalMag in soft or RO water. Check pH after adding nutes. Good luck
