You don’t need that much starter do you? When I’m discarding I just dump it all in one jar, keep it in the fridge and do a discard recipe with it (like crackers, waffles, pancakes, that kind of thing). If you need more starter just feed the one more flour and water. Since they are already in different jars I’d still just dump it all together and make a discard recipe so that you don’t have so much to maintain. Holler if you need more information!
