What do you think of this Soil Mix?

I've been looking over soil recipes for my next grow, my first grow i used just Promix Bx soil. I still have a lot left but will be amending it this time. I had PH problems my first grow. I've found these three mixes for bx soil, hard time deciding, These all looked ok so i tried to make a mix of the 3 recipes. Would you change anything?

I'll be using nutes Jack's Classic All Purpose for veg then Jack's Classic Blossom Booster for flower. Should I nute less since there will be the additives like worm castings and marine cuisine?

Three mixes I've been looking at:

6 Parts Pro Mix BX
2 Parts perlite
2 Parts earthworm castings
Powdered dolomite lime 2 tablespoons per gallon

2 Parts Pro Mix-BX.
1 Part worm castings
1 Part perlite
1 tblspn of FF Marine Cuisine per gal of mix.

60% Pro Mix-BX
30% perlite
10% worm castings

Mx of the three, what would you change?
4 Part Promix soil
1 Part worm castings
2 Part perlite
1 Part vermiculite
marine cuisine 1tblspn per gallon of mix.
dolomite lime 2 tablespoons per gallon of mix
 
Unfortunately no, it was my first grow and I was pretty tight on cash after buying the light set and exhaust fan. So it was just plain Promix-BX soil. Always tested my water PH, about 6.3. The plants didn't really start showing problems till about 3 months in. But by that point they were already in 5gal gro bags. Halfway into flower now, the buds are looking good, but the leaves aren't so pretty. Varies from plant to plant, a combo of leaf curl, yellowing and a purple tint.

Looks like you have a good idea of how to make soil mixes. I read a study that said 20 percent worm castings is what the plants responded most positively to. I'd do 20 percent worm castings, 60 percent promix and 20 percent perlite. Marine cuisine at 1tblspn and lime at 2 is a good ratio. Also kelp meal and beneficial bacteria are both good things to look into.

I'm not trying to be that guy but I think you would be much happier supplementing organic fertilizer for jacks. I own both jacks all purpose and bloom and though they do give plants direct access to nutrients theres no point in building up the soil only to use chelated chemical fertilizer. Blue mountain organics is what I recommend but really any bottled 2 part organic fertilizer would probably fine. Brewing worm casting, compost and manure tea is also a great way to feed your plant.

Either way good luck on your grow it seems as though you have your shit down and feel free to post any harvest pics I'd love to see some.
