Organic FastBuds in 5 Gallon Air Pots!

Unfortunately my last attempt germinating went wrong, I planted clover cover crop and after 7 days nothing was poking through, they were barely a cm down and after 5 days of no seedling i checked the soil carefully and found loads of worms that had eaten all of the clover seeds and my C4 and Purple Lemonade were nowhere to be seen, i made a beginner mistake of mixing store bought peat moss and worm castings but it had worms in it so i will buy more premium supersoil with plenty of perlite. I germinated these seeds in a cup of 0 ppm RO+DI water and then paper towel method until both tails were a few cm long and planted on a hill of soil in my air pots. for the first few months of having my RO system it was always at neutral 7 pH but lately i'm getting 6.2 pH even after letting my system run for over an hour plus calibrating my pH meter, i prefer not to use pH up and down with seedlings as it raises the ppms, the pH will fluctuate with the certain microbes and bacteria i mix with my water to feed the soil, natural is the best way. watering using a spray nozzle Day 1- 2ppm pH 6.2 | seed shells hanging off, keeping soil moist for the clovers. Day 2- 2ppm pH 6.2 | no clovers poking through yet. Day 3- 2ppm pH 6.2 | ^^^^^^^ Day 4- 2ppm pH 6.2 | clovers starting to raise the soil and poke through, both seedlings getting 200 par at 32". Day 5- 56ppm pH 7.2 | Mycorrhizal inoculant, 1 teaspoon per L. Day 6- 2ppm pH 6.2 | slowly starting to zoom out as it grows. Day 7- 55ppm pH 7.3 | Root Roids 1/4 teaspoon per L.
