Plants want more calcium, they want more potassium and they are too hot (thats why the leaves curl up)

Get your grow box cooled down and if possible get more co2 in there. Also to fix the calcium and the potassium you could use blackstrap molasses. It would give you both. Normal molasses would give enough potassium but may not have quite enough calcium.
