nube needs help with nutrients

i found this cool type of nutrients but i cant afford them right now. my plants r about 3'' tall and there just getting there 3rd set of leaves so right now it has the one set of round leaves, a set of jagged leaves with a third set just coming out. it will be a week in the ground tomorrow.(btw there seeds not clones). i was wondering if someone with some experience with nutrients could check these out for me and tell me what week i should use them. the name of the nutrients is "humboldts own nutrients" the 2 that i was looking at are "snow storm" and "bushmaster" please look them up for me and tell me what u think. anything will help.

havent used them, but have heard good things about them.
especially their gravity bloom boost.
i use humboldt nutrients (different company) and love it.

Both of those are just flowering boosters. Bushmaster stops vertical growth and forces them to branch out. SnowStorm is supposed to increase resin production. You dont need either of them yet, but they are a good addition to a base nute system..Humbolt is a great product and i would suggest getting a two part system like Humbolt Master or their 3 part system Humbolt Micro Grow and Bloom, then get a good flowering booster like Humbolt Big Up and use it in mid flowering. I use all these products and have no complaints
