Topped this week and it seems that all of them responded well to it. Think I may have FIMMED pheno #1 though, but that's okay. Starting to see pistils on all of them which is an indication of preflower. Going to stretch for next weeks up ahead and will probably begin low stress training them early next week. Also going to feed next week as well.
So far pheno #2 is the biggest. Pheno #4 has stopped producing strange looking leaves and is growing normally.
