u can put them into flower at any time, u make the decision, however they will not flower until they are mature enough, less veg time= less yield, keep in mind good luck braaHow big are they and how are you growing them?
Like soil, how much light, etc.
Any pics ? We can give you a better idea if we have more information.
Wait until they are 18-24 inches, that's what I do under my 400 watt.They are only two inches tall and have two leaves. Growing in coco under a 600 watt light.
