I mistakenly added the yeast first instead of the bentonite? Is it OK to proceed or should I wait until I can replace the yeast and start over?

Bentonite is used for clarifying the finished product, so it would be added AFTER the yeast has done it's job.

Bentonite is usually added after all fermentation ceases, yeast would be first. How did you proceed?

I added the metabisulphite #3 and #4 sorbate before I added the yeast what should I do ?
