I use sunshine #4 (Soilless mix) for starting, and i cut my Ocean Forest with Sunshine #4 for vegging.
2 parts Sunshine #4
1 part Ocean Forest (Happy Frog works great too)
Mycorrhizal fungi inoculant
Earthworm castings.
Dried Kelp
Jamaican Bat Poop (In the flowering mix)
The flowering mix is the same except that i add High Phosphorus Guano, in my case, Jamaican.
That mix lightens up the Ocean Forest, and improves drainage because of all the perlite in Sunshine #4. The Myco inoculant is already in Happy Frog, but it's not in Ocean Forest, so i add it. The Jamaican Bat Guano increases the phosphorus, because i've always thought that Ocean Forest just didn't have enough Phos to finish up the buds. You'll still need the occasional Micro-nutrient.
This mix works great. Green leaves, no curling, fast growing flowers.
