First grow right? My advice would be don't add anything and don't cut anything. let her go. If she needs nutes she will tell you by leaves looking unhealthy. You plant is great and has everything she needs right now. One of the biggest reasons for a first timer to screw up their grow is to over fert and in other ways try to get a bigger harvest. First learn to grow mj, then learn to grow good mj, and then learn to grow lots of good mj! People get so cought up in trying to produce volume and peak potency that they get ahead of themselves. no reason to add anything or do anything to those plants, they are gorgeous.
