Start of week 5 now concerned with the height its getting other grows of the same strain I've seen biggest at around 86cm, how come its stretching out so far, will this effect my overall yield at all? Can't believe how big they have got barneys say upto 70cm, my first ever grow so unsure what to expect but i think its going well upto now, done a slight defoliation this week and introduced boost to my feed starting with a small amount, appreciate any info thanks, have switched to 12/12 hopefully stops them growing, am upto 117cm and 105cm smallest is at 76cm tall
