Can English Walnut, Pecan, & Almond Hulls Be Used in Potted Plants

I would not, as the trees contain juglone, which is toxic to most plants. I have had just a few make it into my pots, and within a week I was noticing bad issues until they were all removed from the soil.
Now, with proper composting this will not be a problem. But by then the hulls should not be recognizable.
