Yes, you're overwatering. I noticed it a couple pages back and fast forwarded to see that it was indeed the fact.
Prune those up, let them dry out good and dry, then dunk in a Rescue Drench.
Let them get good and dry before you water next. With the pruning and a recovery of the roots, they should start going great.
On Edit: I thought I was on page six, but was on page two. Looks like they've recovered nicely!
At this point, you should prune each branch, from the bottom up, leaving the top 5 nodes intact. They'll reward you.
