Yes I have a cosy place no temp change to water but have no idea really mate I’m winging this one totally. My ph has stayed constant temp is good as long as my electric don’t run out and my bubbles stop
If your pH goes up and the ec goes down each check, she's feeding and your going in the right direction, if it's the opposite then reset the pH to 5.8, and reset the ec so its not so high, it will go in the right direction again, I got fed up buggering about with it, but that was only because my environment changes so quickly and kept buggering everything up.
I'm glad to be back in soil, but I can feel mineral nutrient coco auto feed experiment coming on in the other side of the tent lol. I'm doing some research on what auto feed system to go for
