That could be the problem with the stuck fermentation in its current state - Honey is very lacking in nutrients, it contains almost nothing except sugar and a little water. You'll need a nitrogen source; your yeast nutrient is fine, but if you have any DAP on hand, it would be better.
If it were me, I would put about another 2 tablespoons of the nutrient in about 1 G of water, mix it up, and add it to the fermenter. I came up with 1 G using the old chem eq. M1 V1 = M2 V2, where M are the two concentrations, and V are the volumes. It needs to start out at about 1.100 for that yeast to be in the perfect range. The math works out at needing 1.2 Gallons, but 1 G is safe enough.
0.130*4 G =0.100* V2, V2 ~ 5.2 Gallons,
(V2 - V1) ~ (5.2 G - 4 G) ~ 1 G.
