Are my tops too close to each other ?

Are my tops too close to each other ? Also I'm worried my plants are too tall since I vegged for 4 months, that they'll surpass the 400w light and I'll have to do something about it ? I just flipped to the flowering stage 2 days ago.

NO !!! if ti's to close to you - do a "slight" leaf removal - (no more than 10) and only remove leaves that block the light to the main buds) questions? Great Looking grow !!!!! And they are really not that/well ? close. granted a plant need about 2.5 feet per plant. spread the pots a bit putting the strong side (plant) were the beast light is. ( if you have "side-lights" use them now, they can increae yields by 25%)

Depends on how much head room you have. Could be fine, gonna at least double in height in flower.
Lst some branches down that will help spread the tops and make it shorter

Lookin good to me man. Good job. I'd be flowering pretty soon.
