I agree with Loc Nar. :thumbsup:

Clones are mature as soon as they have roots, so it CAN be flowered right away (unlike a seed). However it takes 10+ hours of dark, for the chemicals (hormones) to build up enough to trigger flowering. So five hours wouldn't do that.

My guess is the same as above,.. Your seeing PRE-flowers on your nodes. Not "full on" bud sites.
