Rather than chemical perhaps it is biological. Things need sometime to heal
and get back on line.

Your biological cycles are off and they take some time(perhaps 2-4 weeks) to
get back. Be patient and keep up on maintenance. Remove/harass the algae as
much as you can. Get your PH down to about 6.8 for awhile and keep it
**stable**. UV won't do nothing BTW. Buy more fast growing temporary plants
Even after you have all of the levels in your tank in the "right range" it
takes some time to build up "tank momentum" and have the plants/bacteria
growing/absorbing nutrients. Once everything starts cycling then the plants
will take off and the algae will be gone for good.
I think many many plant keepers experience this situation at some time or
another but just keeping up on maintenance and being patient will cure most
of it. Many of us neglect a tank or go on vacation at some point. Getting it
back can piss you off after doing a bunch of testing and still no results.
It takes some time to get going again. Algae won't really grow but it won't
go away when the tank has been re-done/crashed some and gotten back up to
snuff until the plants start growing fast again.

Get the ph lower! Say 6.8 or so and keep it there using only CO2.
This is your main issue at the moment. The extra nutrient load can be
removed by water changes.

All good.

Don't remove too much(NO3) of this one from water changes! Fe is a little

Sound a little low for that KH. I got the same KH but slightly higher GH. 
Go to ph 6.8. Your fish will be fine etc with the KH and GH you have.

Perhaps remove the peat? Bring up the PMDD up gradually over the course of
2-4 weeks. Your plants aren't using near as much as before this mess
started. Test for the Fe/NO3 etc for amounts used to se how much the plants
are using, if you wish or you can just watch closely.

You have plenty of filteration and good water changes. I'd lose the internal
filters myself.
