Three of my girls have bad leaf curl on the lower leafs. They seem to be getting better on the upper leaf. I was running my light at 50% have brought that down to 30% and raised my light up to 28 inches. I think the leaf curl is from heat or light stress so backing down to see if that helps. Also have two mini fans giving good air circulation. I also keep my spray bottle and one gallon of water in tent so that its the same temp as air and plants. I am pleased so far plants are growing fast.
@Ddcfc420, I started them in a six pack seedling cube. They germinated in 4 days then put them into pots yesterday it has been one week since they sprouted. I also used a heating mat to help the germination.
