Some Advice / Help Please

Hi all not posted that many times but i hope some of you may be able to help or steer me in the right direction.

i have had my tropical planted tank setup for about a year now. Lately the plants seem to be either developing brown spots and holes, or the tips browning and almost rotting really. i had some pennyworts (i think, large green round leaves) these all turned brown and died quite some time ago, and the rest have been fine for the last few months even surviving whitespot meds about 3 months ago.
I have some swords, and a few others i really cant remember the names of, one set is Rhizome style (think thats right, where more plants grow from the leaf tips!)

the fish: Ancistrus, guppy, betta, neon tetras, mollys, platy, corys.
the stats: ammonia 0.25 nitrite 0.0 nitrate 7.5 ph 7.4 used api master kit just before water changes.
tank: 120L with 600lph juwel internal filter with nitrate sponge and carbon.
Ligthts: 2x t5 highlite lamps 24w each
here are some photos, sorry about my betta and platy, they just cant stay out the way!






Thanks !

what are you doing in the way of fert dosing and C02?

no Co2 and up till now no fertz. Was going to try getting some just to see if it made any difference, but not needed to fert in last year?
