Sounds like over fert. I've burned up more than one with a 10-52-10 Schultz. I found out you should only give that stuff 2-3 during the whole flowering cycle and use 1/2 strength or 1/4 strength.

Looks like over fert too. Leaves curling under, drying up fast, crunchy. Deficiencies won't kill a plant this fast. Pretty sure you burned them up.

The plant in the first post looks too far gone. Pretty much completely dead. Next grow, I would get some better soil, because when you say "soil" is it just soil from outside? Or is a peat mix, store bought? Use nutes with caution, better to under do it than over do it.

Wish I could help more, but the only time i seen a plant look like yours was with over fert.
