Slow flowering?

Due to size constraints and admittedly, a little bit of impatience, i flowered my plants after about 21 days opposed to 28 as i origninally planned, they were getting so big and it is said that the size will double during flowering and i dont have so much space. I've been flowering for about a week to ten days now i believe and there are not any flowers at all, never was any preflowers either, which is what im worried about. I read a few days after starting 12/12 that inducing it before preflowers can cause hermies. Now as days pass i see nothing, they are growing, just no flowers. Is this normal and am I doomed to hermies now?

id appreciate some help please if anyone knows anything.

thanks

starting them that early just makes for a slower start, but 2 weeks to see flowers is rather normal, even for plants flowered after a longer veg.

ive never heard of this starting flowering to early causing hermies and ive both grown for 4 years and have been on most of these growforum for all that time, probably read something mj grow related daily.
