Some sort of deficiency?

Does it really need water everyday?

Could be a few different def, ill let you try to figure out what best resembles your problem

 

Fox Farm has a lot of nutes in it, I always asked growers using it to dilute the mix by 30%-50% with perlite or even sand/gravel, then you can add whatever nutes, within reason as a follow up.

To correct
Flush with 3 times the volume of the pot with Ph neutral, air temperate water, allow to recover in dim light 1x day, then resume under the T5's, or just raise the T5 to 3ft+ of the plant.

As a matter of interest you might take a Ph reading of the runoff after each bucket, using Ph pool strips from your local drugstore for $5.00,,,, as this is soil Ph ain't that important, to you or the plant ....IMO
 
from here same issue: http://forum.grasscity.com/sick-plants-problems/1237509-help-plant-deficancy-i-think.html

 

pH is very important even in soil. But doesnt need to be very accurate.
If your pH isnt in range, or has grown out of range, you needto correct it.

Secondly, youve only used top dressing ferts for the entire grow? Nutes might not be getting all the say down to the roots at the bottom.
Id say You have a deficiency, most likely P or K judging by the pics.

Trial and error man. Flush if you suspect too many nutes, see how she reacts
Water soluble fert if def. and observe.
