White Widow Auto + AutoPot

beginning of this week , water temp was low 15C-16C- I then got a water heater set it to ~20C. The plants seem to be looking way better. I separated the AutoFlower from the rest of the plants , I used FlashClean 4ML in 5Litres for 2-3days. and then started with Rippen 16ML in 5Litres. I use Silicate to rise the pH. so that doesnt amount for much in what it does for the plant.
