Ummm. This is bad.
Is this because too much dichromate?
Or just my bad coating?

Did the plate look like this prior to exposure?

Yup, seems like you put too much dichromate and it crystallised out.

I have a questions.

After finishing coating the plate and wait for 1hr should I put it in refrigerator(in the box) or just store it in the dark?

My plate looks over or under exposed?

Can dcg be over exposed and what it will look like?

After coating you should store the plates in a warm dark place to dry for 4-12 hours. You can store in a refrigerator, but it might cause condensation on the plates. They need to be sealed to prevent this.

Your hologram looks underexposed, overexposure tends to leave a "burned in" effect.

In addition to the under-exposed comments, I think the five minutes in the final alcohol bath seems a bit long. Monitor the final bath under normal lighting. If/when an image appears you are just about done.
