yes, you can top a plant as much as you want while in vegetative growth. you want to stop 7-10 days prior to flipping to 12/12. i top the piss out of my plants (the strains that like it).

a plant can go hermie from being stressed via many factors, but not while it's in veg. a lot of the strains on the market are going to hermie a bit anyhow. it just seems to be the way that it is.
