Well, we are talking about a soil grow here and not a hydro grow. I started out as a soil grower and used a multitude of different fertilizers over the years. The Peter's "Jack's Classic" series ended up as my favorites.
I've used Advanced Nutriets for my hydro growing, and to be very honest, I don't like it. The first grow, AN mislabled the ratios on the bottle and all my young plants died. Needless to say, that was expensive. If you use all the nutrients in their line, which they promise will produce a ton of pot from one plant ... ha ha ... you would be spending around $500.00 per grow on their nutes. In my honest opinion, AN is less in the nutrient business ... and more into the money business.
There are more simple ways and much less expensive ways to grow hydro and get stellar results.
You can use a two-part General Hydrophonics plan:
Just buy a bottle of GH Micro (brown) and a bottle of GH Bloom (red). Do not buy the GH Grow (Green).
0-5-10 for vegging.
0-8-16 for flowering.
Vegging: 0 grow/5ml Micro/10ml Bloom Flowering: 0 Grow/8ml Micro/16ml Bloom
Simpler yet is what I use now:
Pure Blend Pro. Use 15ml per gallon of RO water for vegging.
Use 15ml per gallon of RO water, plus 5ml of CalMag for flowering.
You can buy both the PBP "Grow" and the "Bloom." Use the "Grow" during vegging and the "Bloom" during flowering. OR ... you can just do as a friend of mine does and use the "Bloom" for both vegging and flowering. Now, before you say it won't work, my friend grows some of the tastiest pot I've ever smoked ... and he does it consistantly.
