Yup. Still PH it and adjust if necessary. It should fall close or near to 7.....but I've had a few screw ball measurements with distilled water. All I have ever used. I have a distiller, its kind of slow. Many here suggest RO machine, will produce more water faster. Less expensive than a distiller as well. I'm thinking of trying one.
Of course as per normal, if you add Cal Mag, nutes, etc., you will need to again adjust Ph.
Yeah distilled water not sure . i find it useful to use just filtered water
or even spring water with minerals sometimes tap water i think could serve
a purpose you may want to ad macros and micros using distilled water all the time.
just my observation .
