basic cemcical formulas

ok soo im getting prepared to start my second grow this spring. i have about 300 seeds and still looking for more and taking between 5 to 10 clones of each plant(only females). really what im wanting to know beside the vegation formula of 20-20-20 and the blooming formula for 15-30-15 is there any other formulas i should get that will affect my yeild for the better? that are easy to obtaine threw stores to?

In the vegetative stage, a good 20 - 20 - 20 supplement

In the flowering stage 10 - 30 - 10

but it varies slightly on the flowering stage, depending on the strain.

unless you have a really good plant store or somthing that specializes in nutes for plants. your best bet is to order online.

you can buy some expensive grow formulas, but for that many plants its a waste just make sure they get the right ph, and ratio of nutes.

since you seem to be growing outdoors, just make sure you have an outdoor, large yield crop.
