Everything under the scrog net gets chopped off. Then defoliation through weeks 1-4 sometimes I’ll do it later than the 4th week depending on the strain.
Some plants take it better than others… With strains I know and have run many times before I’ll just about kill the things to get them to do what I want. Usually I aim for a cola per Square on a 5x5 net which is possible with a light mover and defoliation.
