Pleeeeeeeeeeeeease help me, this is my first 2 plants EVER grown and I don't know what's wrong. I had these 2 plants growing in natural soil for a couple months, then people found out about them, so I moved them into a cornfield and mized the natural soil with potting soil. I watered them, AND put liquid fertilizer on them, only to wake up the next morning to find the leaves all shriveled and about to fall off. Heres some pics.

Sorry, but they're fried.

How much of the nutrients did you add? (did you follow the directions on the bottle?)
Did you add the nutrients to water first?
