Hi.
I'm not a pro by any means but 20 discs in a 55 gal, 4-5 feedings is a lot of bio load and 20%-50% water change is just not enough. I got 11 discus in 125 gal aquarium and feed less and unless I change at least 50% water my nitrates get very high.
New discus you got did you quarantine it if yes how long.
What did you treat them with?
Can you post some pictures?
You really NEED to test your water otherwise you're just guessing that your water is clean.
