HI, I use the GH floranova series. It is like the 3 part series brought down to 2 parts. 1 for the veg. stage and 2nd for the flowering stage. Coming to the end of my first grow with this stuff. It is fool proof and the result are fantastic! If you feel the need for a little juicing up you can get the floralicious. Stuff stinks like crazy guess that is why it works. I have friends that use it I myself have not felt the need. Just a mention here I hope with the gear you got that, That you picked up a ph and ppm meters. worth there wieght in buds LOL. Just my 2 cents, good luck!
