What ph should my run off be at?

Just curious what Ph my run off should be at. I’m growing OG Kush autos indoors in soil and the plants are about 3 weeks old. I’ve been using demineralised water on them.

Your Ph should be between 6.3 and 6.8 in soil, with 6.5 being the sweet spot.

Got a picture? At 3 weeks depending. On her size you maybe hesitant to water to runoff

I haven’t watered to run off yet but one of my plants has started to lighten around the edges and I don’t know why .
