I dislike MG but I hear it works fine for some you just can not add nutes. As for clones the longer you wait the better the clones will be for example if you take a clone from mother at 3 months and another at 6 months the 6 months will have more thc and stronger grow. But you can clone the bottoms after I would say 6 nodes are up. Always take bottom clones more hormones.
