Ubi concordia, ibi Victoria

@PaxIlluminare keep records of daily temps and rh both during lights on and off par readings for the lighting used ph measurements EC measurements C02 meter if you use C02 after a few grows you can go back to your collected data and correlate what worked best etc

You don't need to PH balance soil, it does it all on its own as its a living medium. You can PH the water if it makes you feel better going in, or maybe required for the fertilizer options you use. Just don't worry about trying to lower the soild PH via your feeding solution. That is not done via the water its done with the amendments put into the soil. Lime for upping PH and sulphur to lower it, when the microorganisms break these items down they influence the PH of soil. Given you're in containers Don't got below 6.4 when watering and try and keep it under 7.5 as well in the solution your feeding them. Some soils can take a stronger dose of PH down as they have more clay and minerals in it. Keep an eye on the plants and if your noticing PH issues back of the PH down. Plants should do just fine if you keep at it like this.
