Yo! Need advice on what could cause a major PH differential between the nutrient solution and the runoff. I'm making my usual 70 litre bucket up and not adding any PH down. Feeding 1.6ec and 6.4 ph the runoff is measuring in at 1.8ec (good). 5.2ph (bad). Why?? Each fed over 20L.

Hey ICP, what happened is the salt build up has made the coco coir acidic especially when it's dry, try keeping it more moist maybe ? Either that or just keep doing what you're doing until it stabilises and it cant buffer itself out. Hope this helps ! by the congrats on a rocking harvest :rocket:
