First homegrow indoor

I planned to use the following setup for this grow: As substrate, I’m using Biobizz Light Mix with the following additions per liter: 300 grams of perlite, 7 grams of dolomite lime, and Biotabs fertilizer. I used the Biotabs fertilizer according to the recommended schedule. The only things I didn’t use at the beginning were Orgatrex and the tabs, but I’ll add them when transferring the plants to bigger pots. For pots, I’ll be using the Autopot OnePot system with 4 pots including Airdomes. All of the water will come from my reverse osmosis filter system. Initially, the water had around 10 ppm / 6.4 pH / 15.5°C, but it has changed a little bit since then. The ppm dropped to 4, the pH went down a bit, and the water temperature rose to room temperature.
