Swap res once per week no exceptions, you'll be pissed off if something as simple as this screws you out of your crop.. just for being lazy.....
You can top it off with water if it gets low during the week like the guy above me said. Check Ph right after you top off and adjust if you have to.
Add Ph Adjusters in BABY STEPS. Checking each time you add adjuster. A little goes a long way.
(make sure you stir good each time you adjust)
Check PH EVERYDAY. Sometimes it can be stable for days and then get screwy all of a sudden so stay on top of this. You must be vigilant against the PH spike demon!!
Also clean your res every couple of weeks preferably with Hydrogen Peroxide and a scrubber. Rinse thoroughly. This will help you tons.
These Cats are giving you good info. Lots of smart cats on this site.
You want quality bud... don't get lazy.. do the work. Spend time with them, but fight the compulsion to fuck with the res. You can over adjust. If it's within the acceptable range leave it alone. Also bear in mind some strains could prefer the PH a little out of the 5.8-6.3 range.. but it's pretty rare.
And most importantly don't take anything any of us say too seriously. Good Luck.
