hi, ive got 2 buku on the go atm, my 2nd lot of these. and btw uve made the right choice choosing buku, its a beautiful smoke kinda fruity and real smooth and the stone will put any1 2 bed. that curling and twisting isnt normal, i wouldnt say its extreme but not normal, at a guess i would say its overfeeding, maybe if ur soil is rich then use just a plain water feed for a week or 2 and see what effect that has, ur plants being young the soil may be still providing enough nutrient, however on a better note i wouldnt worry 2 much. in my 1st hand experience this is the strongest and most resilient strain ive come across so there shouldnt be any lasting effects. and on the pot size, im with u i like 2 go from my tiny pots for cuttings to my 11litre pots but plenty of people use a middle sized pot aswell, each to their own isnt it. but obviously if these plants were growing outdoors their roots have no limits so 2 say ur pots are 2 big is rediculous. hope this helps and please keep us updated and i will follow this thread so any questions just post em n i will try n help
