No room for water in blender - Help


I just made my first batch of Even Cheaper Start customized for 2400 cal. The 400 grams of corn harina, 120g of whey and all the other ingredients came up almost to the top of my 40 oz. blender. As a result, I couldn’t add enough water to mix everything up. I was expecting to make a batch for 3 meals and then stick it in the fridge. Alas, it looks like I will have to divide the soylent into 3 baggies and blend them individually for each meal.

Am I missing something there? Any advice appreciated.

Here’s the even cheaper start (again, I increased the ingredient list a little bit):
