Id def. go w/ all six if you got the money to spend on those damn Solubles. My grow before this one I just used the FF-Liquid Nute tri-pack and everything came out looking and tasting awesome, but this time around I had the extra money to spend on the soluble tri-pack and wow, it did make a difference. My plants were grown basically the same, in the same dirt, same temps, same lights, same feeding schedule (w/ addition of a couple new items), and with in a couple inches width & height of the last ones. And now my tops are twice as dense, wide, long, & there oozing w/ Tricomes and resin this time also this is about the sweetest smelling crop ive ever had and ive been growing this Blueberry,Ice, Whiterhino strains for about 5yrs now. Def go with all 6 nutes., its not over doing it as long as you stick to the schedule and remember to start out at 1/4 strength then go to 1/2strength and then to full strength nutes.
