How 2 flush

When flushing do you change water everyday and should i ajust the ph?

for what kind of system? soil,dwc,nft,aero,floodndrain,drip...it's all kinda different

hydro bucket system. with clay balls.

then it's mostly pure ph'd water, you don't have to change the water every day but you should watch the PH, depending on how fast the water is drawn up buy the plant, you should change the water before it becomes unmanagable in the ph fluctuation.

but you only need to flush for the last wekk or week and a half if your plant is big
