So, my plant is 3 weeks old today. The conditions are 24°C when Lights are off, and 27°C when the lights are on at the very high end. The RH is 60%. My light is a SF1000 SpiderFarmer LED light that is 30” away from the top of the plant running about 80% of power. What do you think could be wrong?
The strain is a Bruce Banner Auto from Sweet Seeds

If you are growing hydro I assume there was no stunting from overwatering. The leaf discoloration and morphology look to me like a genetic mutation. Just a guess!
