yellowing fan leaves mid flower

Dolomite lime is very slow releasing the cal/mg, it will do more to raise your ph in your soil so be careful there. Plants take less nitrogen in flower and if there isn't enough in your planter then it starts pulling what it needs from the leaves. They also dont need much cal/mg while in flower. If your girls start fading to early then add a little grow back into the mix, but just a little.
