That's called tip burn and there are several reasons why it occurs.

Within some of the following links if it were me the first one I'd check out is that Cornell one called Vegetable ? Online and there are also pictures within several of the other links as well.

So basically what you are saying above is unbalanced growth, but bringing in CA++ and some other factors as well, at least as I read what you wrote.

Hope that helps,
