Looks like she is just N hungry to me. With her being early in flower, the N won't hurt her. If you have Build A Bloom, hit her with a dose. If it's in your EB, do it about 12hrs after you see the rez go dry and then don't fill your rez or 12hrs or so. This will give the girl time to soak up anything if you wash anything into the rez. Fill the rez after that. You should see a color change pretty quick from the aminos in BAB. It wouldn't hurt to give her a dose of Craft Blend with some EWC at the same time.
