4 wpg is a lot of light. You may want to reduce it by about half or more along with the duration to 9 or 9.5 hrs a day. This will help in the long run.

I am unfamiliar with your fert products so I cannot advise there.

I know the experts here will soon chime in and get you going.......

As Gerryd said, cut back on your light. Most would say that 4 WPG is far more than you need, regardless of what kind of light it is.

Do that and watch your plants. You might need to cut back on your dosing a bit with less light.
