curling leaves

[misk]

i dont have pics coz im at a net cafe n shit but the leaves on my plant seem to be curling in and also droop. what could be causing this?

i had a bad case of spider mights and thought it was just them, but the\yre long gone now and its still happening.

the plant is growing in a drip/bubbler hydro system with a 600watt globe.

any help is appreciated, cheers.
