hehe it depends kimmi... ide say use the same company as your using now, just add in whatever you buy, at half strength like with your veg nutes.... i use botanicare... so ide get some blast off, liquid karma. then my non botanicare is some 10-40-40 kool bloom, and dutch master gold max floraliscious 4-0-6 for the first few weeks of flower. or transiton phase.... nutes are what makes the difference between some good weed, and some dank shit that sticks to your window...... my buddies beeng growing the same strain for about a year, and once he gave some to me, with my proper nutes.. he thought it was an entirely different strain.....Pe@ce kimmi
