So I have no idea what I am doing

Here is the situation. I did okay prefishing on Wednesday but come tourney time (Saturday) I couldn't get a fish to the boat. If it was just me, I would write it off as a bad day. This was the theme for my entire club. Out of 17 guys on the water, only 3 guys weighed in fish. 4 total fish for a club! 1 crank bait, 2 shakey head, and 1 fluke.
Everyone of us had the same story. The fish just wouldn't commit to the bait. The strikes we I did get were very passive. This happened on every bait I threw.
I started with top water and they just ticked at it. Even when I just twitched it in place. I switched over to a fluke and had followers but no real strikes. When the sun finally came out, I threw a frog in the slop and pitched a senko into the weeds. I had 1 fish run with the senko, but when I went to set a hook there was nothing.
There really isn't a technique that I didn't try and the results were the same.
I downsized baits, but they showed no interest in the 3 inch senkos nor IKAs.
The differences between prefishing and tourney day a drop in temps of 30 degrees. It stayed cloudy all day on Saturday.

So any ideas why they wouldn't commit? What do you all do when you are only getting soft bites.
