Drooping Leaves - help please

Hey everyone, i am having a problem today after i woke up from my drunken stooper to find my plant in my General Hydroponics bucket system to be drooping during the "on" light cycle, which is different from its normal appearence during that time of day.

heres whats going on

2.6gallon bucket
drip system with ring
6.0ph
flora 3 part nutrient plan

g:15ml m: 10ml b: 5ml
per gallon

plants at about 30 days into vegatative and is 7 inches tall with about 5 nodes and numerous leave sites forming.

when i woke up the plant had drank about half the container of water and the nutrient solution was probly to strong at this point since the ppm was over 1800 with 200ppm tap water. though this never was the case before. the leaves were resting on the drip ring which was covered in nutrient crystals which did burn the leaves somewhat. i cleaned off the drip ring and did a full change of the solution and turned the 400w metal halide on to dry the soiless medium. usually i have it on 18hour on 6 off. and i keep the pump on for 17 hours of light and have it off for the remaing 7 of the light/dark cycle.

THE PLANTS DROOPING LIKE ITS DARK AND ITS NOT

If you havce any info it would be appreciated

Am i over watering? was it just there was to much nutrients cause the water disolved? could it have been the nutirents on the drip ring? should i flush the medium?

Thanks for your time
