thanks for the info "icb"..but my all 3 of my bc dont look to be heavy yeilding,probably due to there crappy life they had when they wer little,,,as your other post about the yellowing..it couldnt be lack of nitrogen as i was feeding it 15-30-15 mg ferts...i think i either over did it or it happend due to i couldnt get out to water them for a week when he had hot dry weather....last time i had checked they where doing good slight yellowness but no im not worried about that...
