those are supposedly good strains, I have not tried them, only read reviews ... whatever fertilizers you use, most people tend to 'over-love' their plants ... they really do best, when left alone, for the most part ... use half-strength fertilizer dosages, and only feed the plants ONCE per week, you'll tend to have better plants ... it's a lot easier to add nutes, when obviously needed, than to try 'fixing' an over-fertilized plant ... happy gardening :smokin:
