Cost, there are about eight million choices now, lots more grow shops and a lower percentage carry it than some other brands... meaning less need to order via Internet but more exposure to other brands, even mainstream nurseries and greenhouses carry Fox Farms now but very few carry H&G, several other companies seem to spend more on advertising, Advanced Nutrients probably spends several times as much, they're not sponsoring forums, my brother's ex-wife's cousin's boy is using Nancy's Nitro Nutrients™ and he's got wicked mean dope every time I deliver a load of groceries so I reckon that's good enough for me, flip a coin, this space intentionally left blank, post no bills, I don't know, all of the above, one from column a and one from column b, if your doctor tells you to take two red pills every six hours but you take six every two hours it's your own fault when you see red spots, why are you still reading this paragraph...
Lots that were popular when there were less choices aren't as popular now. Technaflora has a product called Recipe for Success Starter Kit that sells for, IDK, $35-$45 that's pretty complete. It includes Bloom, Boost, Grow, Grow and Bloom B₁ booster tonics, Awesome Blossoms, MagiCal Ca/Mg/Fe supplement, cloning gel, Sugar Daddy, Root 66, and a mixing chart. It used to be pretty popular. Less so now. Surprise, lol, it's still a pretty complete kit - and it still grows nice cannabis. It's called a starter kit, but many people continue to purchase it time after time, filling in if/when they run out of one individual component.
Some people use Neptune's Harvest Fish and Seaweed products. They're organic and commonly available. Not a real high-yield product line, IMHO, but the buds taste fine. I still usually have a bottle of something or other around that I use as a general supplement once in a while, but am not very likely to use it for a grow again.
I'd just pick a set of nutrients that you feel comfortable with. If you have multiple choices at that point, compare prices, ease of use, or whatever your priorities are. None of them slaughter cannabis left and right
. Most do a pretty good job. Some are... a little thing and you end up using them up quicker. You could compare the various nutrient charts, but remember that a lot of them recommend a pretty strong mix and would be considered a "high-wattage, intense light, high production grow" recommendation that is more than might be necessary. Many grow shops have a house brand. If so, it ought to be inexpensive and would probably be adequate at least as a base.
