I dont make homemade mixes anymore but I have tried many.
For your recipe I would remove the bloodworms.. just feed them separate if at all. Shrimp , herring, garlic, algae and multivits are fine.
I would suggest adding some flakes or ripe bananas as a binder.Salmon is an excellent fish for its nutritional qualities and will bring out reds in discus. Paprika can also be added to bring out reds and as an attractant. You can also add in chicken or turkey breast to make it more economical.
