I use primarily Earth Juice liquid plant foods. The Grow formulation (2-1-1) is quite raw; not refined, and so extremely thick (shake very well). The Bloom (0-3-1) is much less thick, it smells buttery sweet and delicious. I like that there is virtually no nitrogen in it, allowing for a greater degree of customization. I also use Microblast, which is an exceptional micro-nutrient formula. It covers nearly all the micro/trace nutrients (just no calcium). For my cannabis plants I only apply it occasionally as a foliar spray, but I have also used it every watering for tomatoes growing in coir.
I have no plans nor the slightest urge to try any other brands in place of the Earth Juice products I am currently using. But I do incorporate other things into my feedings, including products from Botanicare and Bio Bizz.
I use Liquid Karma (10 ml/gal) in virtually all of the water applied at all stages of growth. It is a sea-kelp derived supplement (.1-.1-.5), with humic and fulvic acids, yucca extract, amino acids, vitamins, plant hormones and also increases soil biological activity helping to feed microbes. I have been using this stuff and admittedly went through a period of slight neglect towards my plants, just not caring for them the best I could; not topping off with dolomite as early as I should have and letting the soil pH plummet. Even so the majority of the plants looked remarkable, lost some lower foliage but that was about it; the rest of the growth was lush green and healthy looking.
Then there is Huvega magnesium/mineral supplement, and the Calplex (calcium carbonate). Use them in conjunction in all watering if you use RO or distilled water that needs more calcium and magnesium. Both are also great for foliar application and a quick fix for calcium or magnesium deficiencies.
Aside from those products I have used Pure Blend Pro Grow and Bloom in coco coir, and use them for foliar on cannabis. I only apply as a foliar spray because I am not entirely confident they are fully organic. Typically I use 5 ml per gallon of Liquid Karma, and between 5-10 ml per gallon of the Grow or Bloom. If all you use it for is foliar it will last you a while.
I have only used one Bio Bizz product and that would be the Fish Mix (2 - 0.2 - 6.6) hydrolyzed fish protein and beet extract. It smells like fish, but I like it. It can even be used on seedlings in early growth and it is especially pH friendly. This is another one of those things that the microbes in the soil really enjoy. I also use Fish Mix in conjunction with Earth Juice Bloom throughout flowering, mainly during the first month. It provides a decent amount of nitrogen and extra potassium.
I did briefly consider trying Bio Bizz Grow/Bloom, but as I mentioned it just isn't urgent. They seems like exceptional one-part formulas, although the Grow has barely any phosphorous and a crap load of potassium in comparison. If anything I might use either of the BioBizz products along with the Earth Juice, not as a replacement.
