4AM, Sour Stomper, and GSCE outdoors

This is my first grow. I have raised beds in my backyard that I am using. I'm direct-sowing the seeds into my bed. I've got pretty good soil, but decided to add perlite, manure/compost and mushroom compost. It's been great to my vegetables over the last few years, so hoping it translates to weed. I live in the southeastern US, where it's pretty much high 60's during the day, low 50's at night. I planted 2 seeds of GSC Extreme (ILGM), and one each of 4AM and Sour Stomper (Meph). 4AM - sown 4/18...sprouted 4/25 SS - sown 4/18, sprouted 4/24 (eaten) GSCE - sown 4/20, sprouted 4/26 and 4/27 The SS seedling was eaten by a slug or cutworm, so I've got a 2nd SS seed in a jiffy pot indoors...hoping to catch up to the others. After seeing my seedling get eaten, I decided to add diatomaceous earth around each of my seedlings each night, and cover at night with a mason jar. So far, so good...as the other three seedlings seem to be progressing along untouched.
