Yeah, I have over watered in hydroton before. Fed 4 times a day when I should of fed 3 tops. I don't know how common Ca toxicity is, but I do know it locks out Mg and N and it kind of looks like it right now. Too much calcium at the beginning stages can stunt growth later. It moves through the plant slowly and accumulates in the roots. Hope that helps.
