Excessive moisture in Easy Agar Tek, Contam or grain soak deposit?

Long time lurker but finally kinda needed a question after not finding an answer from searching. I looked at the stickied contamination list and none mention much about what I am seeing.
Here are some Agar plates I transferred from Agar started with spores. All of the first plates were Potato Flake and Karo Agar and turned out really clean regardless of the excessive moisture and coming from spore prints I took relatively carelessly.
All of the these plates (pictures) are Grain Soak and Karo Agar. I tried to take clean samples to transfer to new Grain Agar, EXCEPT for Plate 9 (tossed it).
This is 7 days of growth in a 78 degree chamber heated by a fish tank heater which keeps moisture pretty high. Other wise my apartment is pretty chilly.
Feedback on what the off white color is on bottom of plate 2, right side of plate 3, plate 5, 6, and all over 9.
Plate 1

Plate 2

Plate 3

Plate 4

Plate 5

Plate 6

Plate 7

Plate 8

Plate 9

Possibly sediment from your grain soak water and agar powder? Perhaps not mixed well enough. That's all ive got buddy. Good news is you can just transfer it away if you're super paranoid.

Is it changing at all? Was it there when you inoculated? Is it on the surface?
GSW does make a lot of sediment, unless you filter it.

What it looks like is the moisture on the side of the containers ran down and pooled on the agar. I felt the cloudy "deposit" of plate 9 and it was slimy. It wasn't like that to begin with and I noticed it slowly grew. I transferred to new plates and cut the "good" mycelium out and threw them into oat jars to see what happens.

Pretty sure if you just transferred plate 8 to a quart of grain, see if you get clean spawn. Then Grain to grain that to 10 jars you'd be in business

I transferred all except 9 to grain and labeled which plates they came from. 8 looked the best and 4 wasn't too bad. Others look iffy

That's bacteria. Try keep your containers upside down to prevent condensation from falling onto your agar. Often condensation picks up contaminants, and can deposit them onto your medium.

Is it likely that all of the mycelium that was in the plates with the bacteria is contaminated? Or will I be able to transfer and isolate clean material?
