Your dosing about 1ml per 10g. Go up to 1ml per 5g for 2 weeks. Then do 1ml per 2g and see how the tanks doing. You may eventually need to dose 1ml Glut to every gallon.
I'd cut those light hours down before you start getting algae issues. Try doing 8 hours but watch and if you see an algae starting back lights down to 6 hours.
