Sea-K Kelp Extract

[4d-Rock]

What I'm confused about is the old and even current pdf says 0.4g/gal which makes the juice pretty dark already, but the bag in the pic says 1-4g? https://greenleafnutrients.com/wp-content/uploads/2017/07/SeaK-Back.jpg

Hmm..That might be an older bag or run of it? When I received mine just after this post I got a plain black bag with no fancy packaging. Maybe they were re-doing it with updated info?

For my current grow I Foliar fed almost daily through veg with a weak mix of 0.2g/gal. I also mixed it in every other watering at a strength of 0.4g/gal. Not too sure yet if it's making any difference, but the plants seem pretty healthy.
