I'm not sure exactly what that yellowing is, but they look borderline overfed with nitrogen. The leaves look very dark. If it were me, I would back off to maybe 2/3 strength. I don't run hydro, but that's what I would do if they were mine.

Definitely too much nitrogen. You can tell by the burnt tips and dark color. The new leaves are yellow because the plant is growing faster than normal, probably due to the excess N. They eventually turn green. Cut down on the feeding.
A little bit of yellowing is fine like on the newest growth, not big fan leaves, like mine which have some yellow tops due to it being the start of flower and the growth spurt:
This is the normal color in veg:

Sorry et133et dont want to jack your post. But also having a similar problem.
Picture taken after 54 hour dark period, second day under 12/12 600w HPS. Been veg under 18/6 400w MH for 6.5 weeks.
Soil - Roots Organic
Nutes - Really diluted Fox Farms trio
Humidity - 45% avg
Temp - 77° avg
The waters PH is a bit high using regular tap water.
Is this also N deficiency ? " PICTURE TAKEN UNDER HPS "
