too late to top? (w/pics)

heres the low down RIU:

i originally was growing these for a sog grow due to my little space and wanting to cram more plants in. i recently got a new house where i will be upgrading to a full room and will have a lot more space for some big bushes...

they are about 2 month old 17 inch clones (thats a 12oz can beside em)

are these now too old and tall to top (with improved results) ???
if not how long should i wait after topping the main stem before going into flower??
or is there another method of pruning/training i should consider?

LST or supercrop..topping has recovery time.

the main stem is super thick and hard already is supercropping safe an such a hard stem? im going to be using 1000w lights so im sure i can get enough light penetration to the lower branches if i train them out away from the main stem...right

I'd pull em over not supercrop if really tough. I train earlier but you know that. Topping will force it to bush but adds time.

hmmm well id like to put them in flowering in like 2 weeks, i wonder if that'd be enough time...

when i grew this strain out last time i used uncle bens method of topping for four branches, yielded 10 oz off the one plant and it finished at only 2ft. tall

anyone else have any input on this?
