Iron chelate and white leaves/wrinkling?

• Iron:
• Dosing: 10 mL Flourish, 0.25 ppm iron chelate, 25 mL Excel, 10 ppm NO3, 0.8 ppm PO4
• NO3:PO4 Cumulative Dosing Ratio: 32.5:3.6 = 9

Notes:
I noticed that suddenly today, the stargrass had new growth that was white, and that some of the new leaves of the A. senegalensis have curled/wrinkled a bit. It seems that a lot of the iron chelate (1 ppm yesterday) causes these symptoms. Could there be some reaction with the iron chelate and Calcium? Interesting.

The angelfish have already spawned again this afternoon. Since the eggs always seem to disappear after two days, tomorrow night, I'll probably try to cover the leaf with netting at night to prevent whatever fish from eating the eggs.
