2nd week flower - between-vein yellowing on fan leaves. Mag def?

Pics below. CFL pics for color and LED to see patterning.

Other than these 3 leaves the plant looks very happy. This is in good soil, week 2 flower following floragro nutes at feeding schedule ratios with last feeding at 600 TDS strength. Everything carefully PH'd between 6 and 7.

Mid-veg this had low PH locking out boron causing twisted growth.

Does this look like magnesium deficiency?

Should I add a little cal mag in the next watering?

Personally, I've never bought into the "every other watering" thing. Truth is, the more often you bath the roots in nutrients the faster she can grow. That's why hydro grows so damn fast. As long as you monitor PH of the runoff, you can nip any salt buildups in the bud, before they can become a problem. A give mine full nutes every watering and they love it.. If PH starts to drop more than a point, then its time for a flush.

One additional complication:

I've recently watered, can I use a cal mag solution as a foliar spray to deliver it to the plant? Should I wait for it to dry out? Water now with cal mag and risk overwater?

Thanks for all input.

Just wait for your next watering. Shouldn't be more than a couple of days judging by their size.
