Critical purple auto (normal color change?)

First grow (ever, not just in grobo) and wondering if this looks normal or if something is off with the nutrients. Had to extend earlier stages as it was a little slow to get started.

@Stephen should the water be bubbling? Could that cause these color changes in the leaves?
