As stated discolouring of fan leaves swelling at base of stem above cube/pellet looking happy and a little gentle pull on clone if it does nt wanna come up its started the process of making roots!!
Big tips-
be patient it ll work in time not in yr time !
Dont be sprayin like a mad man even at all direct to clones/mist ya prop lid !
Once ya cut I taken leave ya girl alone for 3-5days as she needs her peace !
Open slates on prop after the initial 3-5days for a hr and leave longer each day after till ya got roots !
