I keep some small cory cats that get sunken food bits, and the snails get
most of the dead plant material as long as there isn't too much. If I have a
lot of dead or dying leaves I just prune them out. I haven't found any fish
that is really good at eating the dead plant material -- I usually just
siphon it out when I see it.

Sounds to me like a possible potassium deficiency. I had some similar
problems with my big swords until I started dosing KNO3 with water changes.
The K is needed by the plant to help with Fe absorption, so K deficiency
tends to show the same yellowing of leaves that Fe absorption does. Probably
would be best to check the two Kent products you mention and see what they
might be leaving out. I use Seachem's Flourish myself, and add supplemental
iron and KNO3 with water changes in addition to the Flourish.
