Actually, I just started foliar spray 1 month ago, so I can't comment on it's effect. I guess the osmocotes did help since I've been using them for almost a year now.

For seaweed fertilizer, I use 1/2 the recommended dosage, I suspect full dosage shouldn't be a problem for foliar application but that I have not yet tested. I think for chemical based fertilizers, it probably safer to go down at least 1/4 of the recommended dosage.
