Hello GC!! These days I'm having a small problem with my girls as you can see they are turning a yellowish color while the smaller leaves are green.So i think maybe it's from the ph of my soil? So i done a runoff test with plain water(ph balanced 6.6) than I got the first examples of dripping water and it was 6.4 ph. GC what you think is this a good result or? should it be a different result??
