Dont pick based on brands, its overvalued for not reason. U can get nutes pretty cheap with a lil bit of chemistry knowledge.
The only thing that needs a brand is main nutrient NPK, I use masterblend 4-18-36 but u can use greenleafnutrients, jacks nutrients etc.
Then u add these general stuff:
- calcinit
- epsom
-
potassium phosphate (flower)
Thats all u need!!
Additives need also a good brand but u dont need them neccessarily all or any for beginning.
- kelp,
fish shit or aloe vera have a lot of enzymes, vitamins, micro nutrients (any,
biobizz is good too, also in real growers product)
- mono-silic acid helps with stems and therefore u can have bigger buds (grow-genius has the strongest one concentration)
- miccorhizae and bacterias help with roots and also as prevention against diseases (mikrobs, real growers, plant revolution)
- molases in flower (its also in real growers product)
- fulvic acid helps with nutrients transporation faster, also humic but I prefer smaller particles (also in real growers product or
general hydroponics)
- carbon stabilize PH (so, far I ve used just blackjak)
