Kelp4Less in Hose End Sprayer?

Hello,

I've been lurking this subreddit for awhile now but I have a bunch of questions regarding using kelp4less lawn amendments in a hose end sprayer. I've read the stickied post, searched the subreddit, Google searches, etc. regarding how to use water soluble products in hose end sprayer. What I've read is a lot of conflicting information.

So for example, I've been looking at either the extremeblend or green lawn and turf. I've read 1 tbsp of dry product into the container, fill with water, then spray 1000 sqft. I've also read about people creating a concentrate and using 3-4oz of the concentrate in a hose end sprayer per 1000 sqft.

What's the best way? Or what has worked for you using a hose end sprayer?
