They look over watered to me. But only you can really say by the weight of each block.
How many days after you took the clones, did you put them into the larger cubes?the first 4 days i water individually and then transferred to the blocks 10 days ago.
It might feel as if the water is all near the bottom but it's rockwool. It wicks up what it needs to. Don't overdo it! It does dry from the top down, but let it dry out more than you are currently.all the water was in the lower half of the blocks.
Some look wetter than some of the others but to be honest its hard to tell by photo i use 4x4 rockwool blocks and never let them dry out i always keep mine damp not waterlogged also as some have stated if its heavy it dont need more water at there stage in life.
