I was given this recipe from a well known member on here 2 and a half years ago and its worked so well I havent strayed from the recipe much at all. Its cheap and simple and all the ingredients are usually available everywhere. I added powdered fish fertilizer to it is the only thing I did different.
peat/perlite at 70/30 or promix (same thing)
1 40lb bag composted manure (never dehydrated manure it will burn), or leaf compost...that's your N
10 lb bag worm castings (more N)
1 handful dolomite lime
1 handful epsom salts
1/4 cup azomite
1/4 cup greensand
1/4 cup rock phosphate
1 bag horticultural grade charcoal
humic acid, add as directed or leonardite
This will be plenty of nutes with just water for an 8 week strain for the most part. Some strains are cal/mag whores and they require a little more but in most cases this will be enough. Read your plants and go from there. Good luck.
