They are going on 5 weeks this Monday they are @2 feet, one a tad taller then the rest. They have another 4 feet to the light. 4 different strains - clockwise from left front is: Chile Verde, Cocoa Pebblez, Cherry Do-Si-Do and Watermelon Mimosa
Id def go ahead and start them, maybe the genetics but they look a little stretched, id try to keep light closer to keep them compact because they will double in size
