whoa! man you might want to trim them nasty leaves off to try and save that plant. I'm not a fan of 24/7, mostly because the plant needs some downtime to grow good roots.
jtingler is right, need more lighting.

I try to not get water on the leaves, the water acts like a magnifying glass and can distort the light spectrum and possibly cause burns.
Roots make use of nutes, not leaves .
