I started my corn in an above ground raised bed (because I am a newbie) and was doing great dark green and when they got to be about a foot or so I transferred them into a space I tilled up and added manure,epsom salt, and potting soil then tilled it all together before I made my rows after doing so I watered and fed miracle grow, about 2 weeks later my plants started turning pale and wilting, I water about once a day in the evenings I live in Arkansas and the temps have been pretty much in 80s with a lil rain here and there but not much what do I need to do
