Can someone help me diagnose the issue with my transplants?

There are four 1 1/2" openings in the bottom.

I used this method last year as a test and the plants did great. The only difference this time is that I made my potting mix with the 5.1.1 method instead of buying it. There was no way I was going to buy enough potting mix to fill twenty buckets. That's the part that had me concerned was that the mix may have been causing it or something. I'm sure it is pretty cool down in the ground right now.. which will work great for me once the heat comes.
