When using extracts that have not been fully dewaxed, it is imperative that your mix contains some form of diluent to help keep the waxes in solution. You may have seen small particulates fall out of solution as you near the end of your cart. This is a clear sign that you still have waxes in your blend and that you are nearing cart failure. Add a drop or two to your mix and see the difference or indeed use to dilute your carts strength when your not looking for a full power mix.
