Thanks, I started with 5.3 ph 20 min ago. I have to go get some work done so I will let it run and check it again when I get back, then adjust. I already flushed it 3 times but did not adjust the ph. I am still getting brown dust into the res. I'll keep flushing till it clears up. I have time since this was to be for the flowering room and I was going to use a drip into rw for the veg.
What is your opinion on this? Looking for any feedback good or bad.
Better to avoid as many problems up front as possible.
