they are in a mix of potting soil and vermiculite with a little blood and bone meal, since i took those photos they have been under a new 250w M/H bulb instead of the HPS, as for the soil ph the probe meter thing i have isnt working so i bought a cheapo ph tester and will check runoff next watering. i also went a got myself some nutrients today. GHE Flora 3 part, i did water them today with the new nutes, but i didnt check runoff. im 90% sure my mix was 6.3-6.6 going in. only have a liquid tester for the moment
