DWC Pineapple Express Auto by Barney's farm

Hello and welcome to my second attempt to grow in general and in DWC. First grow faild after a couple of weeks because i didn't have a water chiller to keep my water temps in control. Frozen bottles in the tank didn't help. Temperature fluctuations were too big. Now have a Hailea HC130A chiller and hoping for the best. I rinsed the clay pebbles with water to wash out the dirt. Soaked a rockwooll cube for 2 days in pH 5,5 water and after that in new pH 5,5 water with Advance Nutrients Voodoo Juice. First i put the seeds in a glass of water with a solution of 1% hydrogen peroxide for about 18 hours. Then they were placed in a damp paper towel in a zip loc bag. Temps about 24°C. After 2 days they had tap roots 1-2cm long. Transfered them in the rockwoll cubes, cubes put in clay pebbles and placed in net pots. Plastic bottle ends misted and placed over the rockwooll cubes. DLI ~8-9, 20ml of water givem around the cubes on pebbles. Day 1 - Checked on them after 1 day of being in the tent and they look good. Water in the tank is just touching the bottom of the net pots. EC 0.7 pH 6,3. Added a bit of pH- Day 2 - EC 0.8 pH 6,3 Added 1,5ml of pH- to bring it fown to 6,2. EC rising a bit probably because of pH- Day 3 - EC 0.9 pH 6,1-6,2 Looks like pH stabilized a bit. I would like for it to be 5,8 and stable. Leaves are growing a bit and not showing any discoloration. Water temperature is always 19-20°C. Lights on temperature 23°C Lights off temperature 21-22°C DLI ~10 It's fun and exciting to try to grow and i can't wait to see how it turns out. Im opened to suggestions and tips from other growers and we will se if i can finish this grow successfully 😁.
