Thanks everyone for the replies! :jointsmile: The only question I have left is - What about flushing? Do you clean it out completely then? What PPM is your usual flushing res? Both times I used my tap water which is 350 PPM. I let it run a few days until the PPM levels off and then refresh it, but my buds still burn thick and black rather than a fine ash and the taste, while not bad, leaves me something to be desired. Any advice that anyone could give me would be great!

Oh, and the first time I flushed 7 days (2/5) and the second I flushed for 10 days (3/7) and had about the same result.
