I took clones from my plants 2 and 1/2 weeks ago and they are as green and healthy looking as when i first planted them. Only thing is they are not growing any roots yet. I think they were over watered so i cut back to just once a day. Im useing sure to grow plugs an they hold a lot of moisture. at the bottom of the stem they are all brown. If i cut off the brown tip and dip them in cloneing gel like i was starting from scratch would that help? Any sugestions ?
