Hey futuredream45, I would reccommend changing your water at least once during the grow and again about a week/week and a half before harvest. This allows for any excess chemicals, which could have a negative effect on the taste of the bud, to be flushed.

You can also get salt build ups as well. Changing water will prevent this.

When you refer to hp, I assume you really mean ph. What are you currently using to drop the ph level ?

Change your rez. every couple weeks, some do it more.
Otherwise you can get a build up of "salts" that can become toxic to the plants.
This also helps keep th PH under control as The ph will fall as PPM's rise.
