yes they should be starting to flower now or soon naturally. i also had the same things with clones under 24hr light. after a few days they all started sprouting hairs at every node, i didnt know this could happen and these werent anywhere near other plants. the hairs have dissapeared now though. this is only my second time cloning, it didnt happen the first time but all of them did it this time??? this was within days though not weeks.
