I agree: definitely ditch the pellets and the Ensure. For the "just in case" I think it's okay if you put at FEW pellets in the cage in the morning after the gliders have gone to sleep, just in case you can't get home to feed them on time because something happened. Ideally you will remove them uneaten before they wake up, as pellets are made up of fillers and are nutritionally useless compared to fresh fruits/veggies and HPW. I recommend that you stop using baby food, yogurt, and apple juice, except for as treats. Apple juice is never really necessary and is very high in sugar and has preservatives, so I would just cut that out. Yogurt is okay as a treat but it is high in protein, which the HPW already has in it. If you continue to use yogurt, make sure it's a small amount AND that is does not contain any artificial ingredients like aspartame, which can be deadly to gliders. As for the baby food, we keep a few jars in the fridge for an emergency meal and for treats, but it isn't necessary to do that regularly. All you need is the HPW mixture, fresh fruits, and fresh veggies, keeping an eye on the calcium/phosphorus ratio as best you can. (And mealies, yogurt drops, etc as treats of course!) I agree that the instant HPW isn't as good as the others, but it is better than what many people feed. You can use up what you have at least, but I would recommend switching to maybe HPW Original, where you add your own fresh eggs and honey. The glider kids website has an Original HPW version that simply has added calcium, so that you don't have to work so hard to get their ratio up. I don't know about your glider's yellowing but that's my take on diet. When our female was nursing her fur turned straight up brown for awhile even on a very good diet of Original HPW and a variety of fruits/veggies. Nursing takes a lot of nutrients out of them, so it could be just that, or she may not be eating enough of her healthy foods due to all the extras in her diet. Good luck!
