There are several basic rules to follow in hydro: When in doubt, decrease nutes, make sure of your ph, and increase aeration. So I;m going to say less nutes for now because a deficient plant will get worse with less nutes....but overnuting can kill your plants right off so it's always a better bet than raising nute levels "just to see if it helps" Usually a deficiency or lockout will simply become more apparent with less nutes.....helping you pin down the problem as many plant problems appear similar and sometimes all you can do is change things one by one until you find it.

I'd start with 1/2 strength nutes as directed on bottle. Your regular water minus the Britta.. Then I'd add 2-3 ml/gallon CalMag, adjust ph and see how they are looking tommorrow.

Ps ...check out Stinkyattic's Sticky on using RO or distilled water and cal mag. It's in the hydro forum and has tons of useful info about water chemistry.
