So I got a couple medical clones from a clinic in my area. Pure Power Plant and a Dutch Dragon clone I was told. I transplanted them into larger pots with with Miracle Gro potting soil. The DD has since rocketed in growth. The PPP however has grown, but the growth is terribly slow. The leaves seem to be healthy, but all new leafage on the plant is bright yellow. It seems that the leaves turn a healthier looking green after they've matured a little. I wonder if this is genetic. Aside from the strange yellow color the plant seems to be healthy. Any thoughts?
