Newbie Advice Easy Ryder

Hey Guys!

Thanks to RIU ive had 2 successful bagseed grows.
Totalled like 40 grams on the one grow only using 100w cfl

Id like to continue this trend as i start with my first Auto - Easy Ryder Fem

Please just need advice on Soil - im currently using Cocopeat Potting soil & Perlite.
What i need is the most basic organic mixture i can get.
I dont want to buy a million things and get confused.
Advice on what to add to the cocopeat soil?
Ive previously been throwing in like a handful of fertilizer without knowing what it was
this kind of burned my baby plants and slowed growth.
How can i minimize this? what are the correct NPK for organic ferts and how much ratio to add?

lets assume i have a 3gallon pot - what ratio do i mix cocopeat to ferts?

Thanks Dudes
Much love

hay man, thanks for the info what ratio should each of those be mixed in? ive tried using "Some" and i burn my plants a little.

Heres a link to the super soil (https://www.rollitup.org/t/2010-revised-super-soil-recipe.338384/).

thanks a stack man!
