i do a combination of 2 parts fox farm ocean forest 2 parts fox farm happy frog, and 1 part pearlite. i can go all through veg no problem and minimal ferts in flower for the first few weeks. though i still hammer the bloom ferts to it in the later weeks. not worth missing out on the explosion of growth. but ya there are a lot of blends of ferts and if you want to give it an extra boost you can always add some marine cuisine to recharge at transplants.
just check it out
