Normally a plant has a growth spurt when switching lights to 12/12. I think you still have another week of noticable verticle growth then the plant will concentrate on reproduction (buds )
as i said its my first grow, well first time i have had a plant in flowering so i dont have anything 2 compare it 2. thanks guys. another question... i have 2 clones from a friend which are 2weeks old and both have roots so i put them in larger rockwool cubes until my m8 gets back from holiday. will this be ok? they seem to have some white near the leave tips. is this going 2 be a prob? can post some pics if you need.
