If it's an auto yes if it's not a lot of people will say no .my personal preference I wait until they have 5 nodes. Then top and start training then. auto I would start training now.lst is not recommended by many if you grow auto I'm pretty sure you growing photos but idkNow to start LST where do I tie down or lean over or should I wait the 5th node is coming up now took the plastic off the LEd thanks for that tip! Y’all are the best! Happy Growing!!
