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 .
