Just my opinion, but when I have anything over 240w LED, I keep the power down just a bit, it's more efficient (apparently they say) and I think may be contributing to your issue. I had a SF2000 I forgot to dim once in flower and every plant was green and loving life except this one, I couldn't figure out why. Swore up and down it was improper feeding etc, but something simple as dimming 20% fixed my issue.
This is speculation of course, your problem may actually be nutrient or pH related, but it's best to start at a simple step, see if you get improvement, etc.
I'll definitely take that into consideration. I think it would be strange if that was the issue though, as the intensity has been set at 100% during all of flower, and they've been this close to the light for weeks now--I don't know why all of a sudden there would be yellowing beginning. I'm thinking more along the lines of maybe I've been pushing their Bloom nute too hard, or adding 2 ml/gal of The Rock Resinator may be pushing the P&K too hard
