I believe its 1.060 so you might want to cut it with some water to get it closer to 1.040. There is some junk in it other than malt though. High fructose corn sugar for one so in a pinch it works but I would not use it all of the time. There are other brands besides Goya so perhaps there are more pure choices. i will have to read the labels I guess.
The yeast nutrient can't hurt any but I rarely use it.
