but if it is what im thinking you shud be fine... when i first started cloning i thought the same thing. after the cut the cuttling is in a bit of shock and thinks its dieing so it tries to force flowers. dont worry though after roots the veg on that light schedual.
did you take the clones or get them from someone else??
my guess is that the plant that they came from was in flower, therefore the clones would also be flowering.. just put them under 20 hours of straight light and they will go back into veg mode in a few weeks or so..
