The yellowing leaves I can see are older fan leaves, and they're just old and have done their job of kick-starting their bud site - normal. I can see some signs of old nute burn on the tips of some leaves (yellow/burn tips). All in all though, they look ok for week 3 of flowering. I have a feeling that when you start measuring ppm&ph in your next grow, you might find your ph is a little higher than is recommended.

Are you using the same soil in all 3 pots? It could be a deficiency (or surplus) of nutrients in one of the pots. Or PH issues. Have you tested the PH of the run off for all 3 plants?

I can barely see any detail in the video or HID pictures. Heat stress does not produce yellowing like that. You give us no pH, nor EC/PPM, so I can't say for sure if it's pH relates or too much or too little feeding. Now, yellowing during the stretch is usually due lack of nitrogen; if that it's because lockout, wrong pH or low feeding, I can't say. If the leaves have also brown spots, then it's not N deficiency, but K deficiency.
