I would say it depends on how and where youre growing them, I started mine inside for a few weeks, re planted outside , used foliar bug spray at night along with all organic nutes at full then half. This was my First Auto grow as well as my first grow in many years. I did nothing to the plants as far as cutting , bending ,pinching etc… just let em grow and see how they grew, they did well even after a good beating from mother nature. Next grow will be generally the same with a few amendments to the plants (FIM) cutting etc… There is A lot of info on the web on Autos, and a lot here too, wait and see what other people say on here, ph your water and Don’t nute too soon.!!
