I can also confirm this bug. I have a fairly large inverted V shaped automatic farm that was working great. I noticed about 2 weeks before the 1.14 update (Windows 10 Bedrock Edition) that it had slowed down considerably but not enough to scrap my farm idea and figure out a new one. As of the 1.14 update however it barely works. I also have a small lake that I converted to kelp farm growth as it is great early game and I harvested this to help my main farm and it has yet to grow back fully two real game playing days later. Normally it would have grown back in less than 10 minutes of game play and filled my small lake to the brim.
