A number of us here think first year Mel's Mix has insufficient nutrients to support good growth. Start fertilizing with liquid and see what happens.

I agree about the need for fertilizer. My first year Mel's mix fill was producing yellowish plants that did not grow well, so, we added liquid fertilizer to the beds, as well as liquid sevin spray to take care of the bug holes in the leaves.

That was less than a week ago, and, squash is now green and pepper plants are getting there. Tomatoes planted from seed have finally started to grow. It has really made a difference.

In my own case, I've worked for years to amend my native soil, that I didn't want to just lose all that effort when I made my "Mel's Mix". So, I left the boxes open on the bottom, and just worked Mel's mix into my existing soil. This eliminated a lot of problems with Mel's mix not supplying enough nutrients in the first year. My native soil (primarily clay) is actually very good, especially after 5 years of amending and amending and amending with compost and other organic matter. My first year I had to look hard to find worms, now I need to only turn over a single trowel of soil, and I can find a half a dozen worms! It's a great thing!

Secondly, I would be very careful with the heat down there in Texas. Radishes (and most root crops for that matter) are cooler weather crops, so they might have gotten fried in the sun.
