this is my second grow.

bottom leaves of girls are going completly yellow. I've tried giving them fertilizer but it hasn't helped..

I'm thinking it might be the pH. How would I alter that? I've heard of dolomite lime?

They're nearly 2 months veging. Son T Agro 400W HPS

Have just shown female pre-flowers so I don't want to lose them!
