Can I Get a Dry Weight Estimate?

That'll be fairly hard to be honest. 1 because they still have to grow and 2 we don't know the density of the bud.
I've estimated plants in the end and some have been on point whilst other have been anything from 10 to 20 grams out.

 

Wet weight is 3x the amount dried sometimes 4x so yea take what you see and divide by 4

 

Typically 4-5x the weight. Expect about 20% of wet weight and be happy if it's higher.

 

No telling what YOU will get.
Also your plants look very strange.
But you can expect to lose anywhere from 60-75 percent of weight from the drying/curing process.
So if your plant finishes with 100 gs of wet bud, you can expect 35-40 grams dried.
