Hi greetings to Capetown, and congrats to legalization. Ok back to your plants. i think your growing medium is the problem of your grow, i looked through your diary and your girls looking from beginning very limy. There are two Possible reasons. Your medium got the wron g ph so your plant cant get the nutrients in the soil. Second: the medium is " to hot" that means is to rich in everything. so my recommondation is.... get an ph and Ec meter an measure the runoff of your soil.I think you plant wil stay small. But check ph and ec of you growingmedium to have a result for the coming grows. The choice of the soil and the genetics is very important in growing automatics. You have only a small time to grow and evrything got to be perfect. feel free to look into my diary " cookies for me" there you sfind a lot of nice reciepes , especially for automatics. Happy growing
