I use AN Rhino Skin which is a silicon base nutrient with K in it. It help your plant build chlorophyll and stronger cell walls to prevent stress from heat or cold. Also makes you plant branches and stock more ridged for later on in flower to hold up bigger buds and it also promotes bud growth. I use this from start to finish. Carbohydrates since in coco/soil I use Botanicare Blackstrap molasses. Boost in sugar and also feeds the soil. Bio Root I use to promote bigger root zone and also it has stuff in it that they use for HiBrix growing. I use GH CaMg+ Other AN products would be Voodoo juice. Mostly Im all GH. its goo stuff and cheap. My base nutes are FloraNova. Now that is packed with everything. Other companies sell it as additives. I mix and match what I feel is certain nute companies best products vs the price and if its any different from whats out there thats cheaper.
Like shooting powder is the same as GH dry kool bloom but GH is cheaper. Samething with carboload and sweet raw. one is just cheaper than the other.
I wont compare Bio root with voodoo juice but theres GH Rapid Root ENHANCER and thats cheaper than voodoo juice. But I stand by both of them. Also house of Garden root enhancer
Im not so worried about buds, im more of a veg person and roots kind of grower. The flowers will come when they come. Veg is more important to me.
