How many gallons in rez?
How many plants?
How often do you water?
Little more info..........

Best rule to stick to is.............. CHANGE YOUR REZ ONCE A WEEK

do u add water everyday to keep rez level up??? then evry week when u change ur rez add nuits all over again??? i kno when the water is low u shouldnt keep adding nuits right???

every week or two

3 weeks but i monitor the water (ph & ppm) & use h2o2 faithfully.

I use fox farm nutrients, and i follow what they say. I change the res, every week or every other week, according to what it says. I also follow their flush timeline, unless my plants show signs they need it earlier. If you want to play it totally safe, do every week. If you do every other week, make sure you top it off with a nutrient/water mix. Some people only change their res once, between veg and flowering. They just always top it off, and get the ppms back to what it should be.
