I have since changed to a different bulb. A CFL bulb that's 6500-K. Are the yellow leaves due to the lighting or is it not getting enough nutrients? The tank has nitrates but always tests zero on phosphates. (Hanna 713 meter)

Almost looks like chlorosis, which is lack of green chlorophyll. If I were to guess it would be due to lack of light and nutrients, emphasis on the nutrients. Are there fish in that tank with the mangrove, and are you doing water changes? Can also be caused by root dmg if you been moving it around at all.
try dosing
small amounts of iron, manganese, zinc, and/or nitrogen and maybe upping the amount of light
