That is ok to start with but personally, like serendipity, I'd increase the fresh veggies so they have some everyday. My general rule when it comes to quantity is a portion no bigger than their head. There heads look bigger than what they are so don't be fooled!
I do 15g of dry mix everyday. Then 1 day a week I don't feed at all, that way if there's any bits they don't really like and tend to leave, they go and find and eat them because there's nothing else. Keep an eye on the board though, if there's a lot, don't feed for a day or two so it depletes, then continue as normal.
