how to use a nutes chart?

well im new at growing and i have an aeroponics system, want to know whats a good heads up on the pros and cons, thank you. i bought some Humboldt Nutrients the 3 part (micro,grow,bloom) any one know what i should look out for?
i will have them under cfl till they are big enough for the flowering stage.
thank you for ur time.:rastasmoke:

How many Lumens per sq ft ya got? That will make a difference and be sure to keep lights close 2-3 inches. Humbolts pretty good so you should love the results.:)

i got i got 3800x2
4x3.5

and thx for the res...
