I have two socal masters and four bubbaxmasters in the beginning of week three of flower. Theyre under a 400w HPS in a ebb and flow with AN nutes. I want to trim off some of the lower branches that arent getting alot of light and have very small weak looking flowers starting. the tops have nice tight little flowers developing and want the plant to spend its energy on those but I dont want to shock my plants or stunt them. Is it too late to trim these now or can it be done say over a week or so taking one a day? Any help is appreciated.
