If the black ends are just on the hulls, don't worry about it. It can be something as simple as a varietal trait, could be sunburn while the crop is still in the field, it may be weathered from the environment. If the actual seed is starting to turn black, you have to peel the hulls of, called perling, to see this. You are allowed up to 0.5% of the seeds to have this. If there are 30% of the seeds that are affected internally, then there is a very big problem with where you are getting your malt from, or the stuff you are getting is feed barley and has not been accepted as malt.

Heated kernels, allowed 0.5%

The one on the bottom right is a good undamaged kernel.

Smut kernels

Fusarium Kernels

If the black looks like these, and as you say 30% of the kernels are like this, this would not make malt. Smut is useable up to 5 kernels per kilogram, and fusarium is usable up to 0.2%, anythin over 1.0% does not even make good animal feed, as these contain toxins that can cause feed uptake problems in the animals.
