" I had recently ordered instant HPW from exotic nutrition (still waiting on it)."
Just wanted to confirm what Cameron said. Most people in the glider community agree that food and snacks from exotic nutrition are crap. Which is saying a lot because the glider community rarely agrees on anything.
The glider diets from there have fillers, gliders are known to gain weight and still be hungry on the exotic nutrition's hpw. There have also been bugs reported to be in the diet ( on a group on fb ) and there shouldn't be bugs in it. I'd suggest returning it once it arrives if you can.
Many new owners buy it thinking it's a good nutritious diet because HPW is spoken of a lot on forums like this and facebook groups. It's a very common issue.
What they don't realize is there are a few different kinds of HPW diets. If you don't know which HPW they are referring to you won't know if it's a good one or not.
Critter Love hpw actually did a huge name change/rebrand for this very reason, to separate itself (a good quality diet) from a bad quality knock off because people mistook exotic nutritions hpw for critter love hpw.
This is a very simplified break down of the differences
HPW (High Protein Wombaroo diet) - where you buy all the ingredients separately and measure it out following the recipe.
Critter Love has different formulas of hpw..
1 Origional Hpw which is basically the same as the hpw above but you buy all the powder ingredients from Critter love and buy the fresh ingredients locally.
2 Instant hpw all the ingredients are powdered you only add water.
3 Breeders formula hpw specific for breeding gliders nutritional needs.
The critter love diets are to be fed with the critter love salads which have been formulated specifically for the hpw diets.
Then there is GOHPW which is hpw with green juice added and "reduced sugar"
Then the exotic nutrition hpw they have a powdered and an already made in a jar instant hpw with different flavors.
Glider diets are very confusing at first especially the hpw's as you can probably understand now, at least for me they were the hardest to figure out. The benefit of what Critter love has done is to make HPW easier to understand and easier to get the right ingredients which takes a lot of the guess work out of it.

The critter love site has a lot of information on it and explains the hpw diet better than anyone else can. Peggy is also very much involved in the online glider community on facebook and is always available to ask questions about her diet, which is very helpful when starting a new diet.
***One side note to be aware of if you stay with a hpw diet is the bee pollen. If you use a diet that calls for whole bee pollen in the recipe make sure you explain to your gliders vet that their diet has whole bee pollen in it. The reason is whole bee pollen can be mistaken for parasites when fecal testing is done and some vets do not know this.
The instant critter love uses ground bee pollen and will not be mistaken for parasites.
"apples, banana, eggs, carrots and water cress"
"They seem to like the blend but I was wondering if they get all the nutrients they need from that."
Short answer, No they will not get adequate nutrients from that. However, your kind of on the right path and I understand it's temporary until you get them on actual diet plan.
Again as Cameron suggested temporarily you can feed
1 tablespoon protein per glider
protein,
yogurt - NO 0 or low fat yogurt, no artificial sweeteners. Fruit flavor and or real fruit chunks in it is ok but is NOT a fruit substitute
eggs boiled, poached, or scrambled. No oil butter or seasonings of any kind.
boiled or baked chicken or turkey we stay away from beef and pork because they have higher fat content again no oil butter or seasoning.
1 tablespoon fruit per glider
apples, grapes, cherries, blueberries, melons
1 tablespoon veg per glider
peas, carrots, green beans, corn
rotate one of each category so the gliders have a little variety and get different nutrients from the different foods until they get on a stable diet plan. This is NOT a adequate long term diet.
