Hmmmm, afraid it's pretty hard to say if you can't count ppms but to each his own as my old man always said. My only real advantage of waiting to lst is that I only want to do it to the females given space, lighting, and most of all my lack of work ethic. The males can pretty well blow off in my book. Right now I'm growing from seed not clones so until i go to 12/12 and determine sex I'm not working on anything. Period. During the veg stage they either grow like they are supposed to or I drop a light on them (j/k)
