Any tips for using fish aminos as a foliar spray

I just got a jar of fish amino fertilizer and will be applying it as a foliar spray to my fruit trees, berry bushes, and vegetables at a rate of 1 tbsp/gallon. Im am going to be applying it to a bunch of different trees, including apples, stone fruit, pawpaws, elders, currants, gooseberries, persimmons, honeyberries, pears, hazels, chestnuts, walnuts, and more.

First up, are there any cases in which applying fish aminos could be harmful to tree and shrub fruit crops?  Are there any trees which might become more susceptible to disease after it is applied?  When in a plant's growing season is it most useful to apply fish fertilizer?

What about veggies?  Should I steer clear of lettuce or other edible leaves?  Are there any veggies which don't do well with added fish fertilizer as a foliar spray?

Any other first hand tips?

Thanks!

I'm not 100% sure what "fish aminos" means but I will warn that fish applied foliarly can cause photo toxicity so I would apply it after direct sun was over for the day.

The only other advice I can offer is that fish extracts seem to pair really well with seaweed extracts and worm byproduct, so I might think of making a little tea with fish, kelp, and castings

To be honest, I'm not sure either.  It was gifted to me and Im unable to ask the person who made it.  It may be a fish emulsion + molasses.  

I'll give the Kelp + fish fertilizer a go.  If I am mixing both of them together, should I cut back their concentrations compared to if I were applying them individually?  As in, if I normally would spray 1 tbsp kelp/gallon or 1 tbsp fish/gallon, when I spray them both at the same time, should I do 1 tbsp kelp + 1 tbsp fish in one gallon of water, or should I cut back on the concentrations?

I know I’m a bit late but maybe useful for the future!

Without knowing specifically if it’s a fish emulsion or true FAA (as in the KNF recipe) I cant say too certainly, but if you have FAA or the ability to make some, I can enthusiastically recommend it as a foliar spray. You don’t need much at all, I use it at a 1:1000 dilution (1mL per L). Pretty much all plants love it, I use it on leaf crops but I generally don’t spray anything in them within 2-3 weeks of harvest. I actually like it more as a foliar than by watering it in, as I feel it’s a more direct use and as long as you’re getting the undersides of the leaves the plant harvests it effectively.  

Just as a side note, I also always use a little LAB with foliar feeds. LAB gets watered in too which is the most effective, but if you don’t get good airflow in your site then the LAB will help prevent mildew which can really take off when you’re spraying with sugar solutions.
