I went to the normal 45 days with it & thats when things got fuked up . The indicas didn't mind the extra but the sativas really suffered .this last run i started tapering off at 30 days & it was a much better budset . I am curious as to a PK boost after i start tapering though . haven't done it yet ....not sure i will .Beautiful girls, Dan! The only thing that I would add here is that in the feeding instructions, V+B suggests cutting the nutrient levels back after 3 weeks instead of the traditional way. I've never run the EC at full strength past 28 days, so that may be the reason that I haven't seen any problems with airy buds. I'm still struggling with cutting the level down at 3 weeks instead of 4, but I need to try it sometime!
