are you trying to veg+flower for a total of 2 months? or flower for 2 months? if you only have 2 months, you should SOG that way you can go from clone straight to flower without vegging.
easy, if you dont want to top, just add a flowering additive called phosphoload. not only does it stunt the growing height almost immediately, it promotes bushier plants and tighter buds. i think you onl use this the first 2 weeks of flowe.
sure, use it on bushy plants! it promotes almost immediate flowering, not just stunted growth. i am using it on my purp kush which is a short bushy plant by nature and it is fine!
