Sorry dude cant help you as i only grow in soil.my ph keeps going up. i set my ph at 5.8 and it goes up to 6.2 after one feeding and if i let my nute mix run a second feeding with out adjustment, it goes up to 6.4 ph. my tds meter has also gone up from 600 ppm to 800 after 5 feedings from a 3 gallon resivoir. what do you guys think is happening? I'm sure the reason the ppm is going up is because the plants are drinking more water than they are consuming nutrients. But what is the deal with the ph keep going up? is it because of the coco you think? this stuff is supposed to be ph balanced. Does anybody have any ideas?
I only just started bothering to ph test my water a week ago.
The only thing i can suggest is to flush weekly and you may be right that they need more drink and less food.
Try raising the humidity with a few dishes of water evaporating if you don't have the equipment
