Okay, the little Sansi 15W has more power than I thought. I burned the leafs a bit. Switched to the SANlight, adjusted hight and also gave them a bite more space to spread their toes. In addition, started to feed some delicate BioBizz juices.
Plants are looking good bro! I would wait for a week to see if more leafs need to be removed. The leafs are the plant's source of energy and the more leafs the faster it grows.
