Robertsanswered grow question 3 years ago Hey there I am growing in a dwc at the moment, your ph will fluctuate as plant uses the nutrition. It will get start to swing more if the nutrition amount is not at what the plant is using. So if Appling right amounts with your ph reducer or ph increaser it will stabilize for longer time spans. So if ph is increasing it wants slightly stronger nutrition. If ph goes down the nutrition amount is too strong. When you hit the sweet spot it will very slowly rise if any. Hopefully that helps and happy growing 🌱
