I have used several different brands through the years, but always tried to master 1-2 nutrient systems before changing, much like you have stated.
I started with AN 3-part, Liquid Karma, Fulvic acid, Calmag+; Then after I found that AN basically copied GH 3-part; I converted to GH. I stopped adding all kinds of additives; Settled on Liquid Karma, which provided Fulvic and Humic acid, and Calmag+ because, Marijuana wants more CalMag then offered in GH 3-part.
I tried AN Products a few times; like Iguana; Which killed everything I tried to grow. YUK! I got to thinking; These guys are trying to sell us on too much stuff!
During this time I started a Commercial hydroponic greenhouse. I learned how to mix my own nutrients from 50ln. bags of minerals and have my own “chelated” Micro nutrient formula (Clear Blue". I have 2 customized solution recipes that fit my personal taste, and I can grow anything.
I have always liked Botanicare Pure Blend Pro for seedlings and small organic grows; It works great. This past year I experimented with Pro Mix BX as a start to finish grow medium (experiment), and after propagating and vegetating with Pure Blend Pro; I bought Botanicare CNS17 Bloom, and Ripe. I achieved approx. a gram per watt, using a 400w Ipower digital lamp system, and an old Diamond self contained 250w hps for side lighting. inj a 4x4 tent.
My favorite nutrient to date has been DutchMaster Advanced A and B, Grow and Bloom; With Additives: Zone, Silica, and MAX Bloom. This concoction turns out to be very similar to my personal mixes in regards to type of minerals used.
I would be remiss, if I did not include Marijuana Booster. Available here in our shop; This Nutrient system is the 1st Nutrient system in the World to openly state that; “These nutrients were formulated to grow the most ultimate Marijuana plants on the planet!” :mrgreen:
