Super Soil and adding PH UP/DN?

[Foxtrot7]

My 5 girls are growing in a bathroom in Greentree Ultimate Blend super soil. I didn't realize it was considered a super soil until I was already committed. I've been watering distilled water PH'd to between 6.5 - 6.8. I came across an article that said not to use PH up or down in super soils, They all seem to be healthy at the end of week 3. Should I change to straight distilled water and not worry about the PH?

Why are you using distilled water?

I thought it would be best since my tap is loaded with crap. Should I not?

From what I understand about supersoil grows is that pH'ing isn't required. The soil buffers whatever you add.

I've been watering them this way since germination. Do you think I should stop and use the water straight out of the jug now, or is it too late?

Thanks. I checked them out and of course learned that you shouldn't use distilled water. Figures. My tap PH's at 6.8 so I'll be using it from now on. What I didn't find is if it's okay to use General Hydroponics PH UP/DN. Do you know if it's okay to do so?

I use GH UP/DN to ph my water/feed to 6.5 then check runoff PH for same or at least 6.3 - 6.8.
