thanks hydro

the biggest ones have been under hps for 17 days now and are staying nice and tight,and i've even got some tiny pods forming between stem and branches,though they are ever so tiny

one of my small purple tops is growing weird though,it appears to have no growing top,the 1st set of true leaves appeared then as the 2nd set opened it became clear it is just 1 rertarded leaf,and the main stem has in effect become a leaf stem,it's feminised so i'll let her grow see what happens,i'll get a decent pic of her later
