Your medium:
.7) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it. (vermiculite, perlite...) Black Cow brand humus and manure with perlite added (2 parts soil and 1 part perlite)

Vermiculite holds water you already have peat so with both the soil will hold too much water. You need a soil that lets you feed the plants without water logging because the plants are heavy feeders and will use the available nuts from the soil very fast so you will need to feed them often but you can't if the soil is water logged. Make sure that the manure is composted and add some worm castings but not too much, good luck
