What’s wrong with my grain jars?

All three of my grain jars are looking really weird compared to what I thought Natalensis was supposed to look like. The growth looked normal at first, tho the mycelium wasn’t very thick, it was still fluffy and normal looking. I did a break and shake a couple days ago now and it looks super weird. It’s definitely colonized nearly the whole jar, but there no volume to it or connection between grains it looks like. What mycelium you can see in pictures just looks like a crust or something. I was doing an experiment with different levels of corn syrup in each for drippy corn tek, with one jar having none, and it looks the same as the others. They were hydrated at 15psi for 25 mins then left to cool for 35 mins after being taken off heat. They all have a little bit of vermiculite in the bottom that has spread around from being shaken. The only weird thing in the process was the Lc syringe, which barely has any growth in it. There is some, but you may not be able to see it in the picture.
