My first grow I toom some clones off of a flowering female that was two weeks from harvest. It took them two weeks to root and then it took them like 3 weeks to reveg.

ALL throughout the plants cycle(veg through flower) it would grow a little tle bit of resin on the fan leaves close to the stems, I mean sticky, smelly thc resin.Its almost like the plant was still kinda in flower and trying to create thc.

I dont know about a seedling having thc on the leave, but i definatly know that my rejuvinated clones did.
