The faster the leaves grow, the lighter the new growth is before it greens up.
That's why you'll see a lot of lighter growth at the start of the stretch before flower. The growth speeds up after watering, so it's lighter for a bit. At least that's my hypothesis.
When those plants were drooping earlier, was that just after lights on? It can take some of my plants a while to "wake up" after lights on, and they offer droop a bit right before lights off as well.
