The trouble with those rocks as that even if you thoroughly wash and rinse them, some of them may still slowly dissolve as time passes, and believe it or not, what might seem like a slow process and not much soluble minerals from the process can actually be enough to poison and kill the plants in time.
If the rocks are all quartz, that would be fine, but if they include sandstone, limestone, many kinds of conglomerate rock, marble, etc., they are relatively soft and will slowly dissolve.
