Seems more like macronutrient deficiency. Nitrogen may help if you want darker growth, but your tree is flowering well, and that's often the downside of adding nitrogen to trees in FL.
I do see what appears to be PM on the blooms, so there may be some spraying you could do to help with that.
For nitrogen you really don't need to apply to foliage, as it's soluble over a wider pH range than are many micronutrients.
I've foliar fed mangoes many times, but it's easy to apply too much. Your seaweed extract is probably fine, and is likely to supply Potassium which is a good thing.
