Wedding Cake DWC (Bridezilla)

I’m started the seedling on 7/3 (after germ to get a tap root) with a smaller grow light. It popped out of the shell yesterday. Once the first leaves start I will move it to the grow room with the 600w lamp where my other plant is. It seems like the seedling grows best if I put half a water bottle top over it to retain humidity and heat. Named it “Bridezilla“. 7/7 first single leaves looking rough. If she doesn’t improve with the next leaves I might toss it as a dud. 😩 7/8 looks better after lowering ph to 5.5
