Liquid Kelp is great for foliar sprays...so is most brand of fish hydrolysate... Fulvic acid is great too. Organicallydone.com have some great products.
Getting a dry bag of kelp and making your own fresh teas would give you a better quality foliar feed though. A lot of good stuff gets lost in the bottling process.
SCREW Advanced Nutrients. Biggest rip-off in the business, I really cannot believe the kind of marketing claims...should be outlawed! If you absolutely need to buy something in a bottle for foliar feed in one step, get some Liquid Karma.

Or you can just get that for 15-20 dollars. and at 1/16 of a tsp per five gallons i would say it's probably gonna last you a lot longer than a bottle of Liquid karma.
Or you could use household (non antibacterial) dishsoap. It does the same thing. It is also a surfactant and wetting agent just like yucca.
Liquid karma probably only has 1/4 a cup of kelp, a teaspoon of yucca, and maybe a couple tablespoons of Humic Acid (and probably humic acid from leonardite, not the good kind). And it costs what 20 or 30 bucks for a quart?
Granted...a bag of dry kelp, yucca, and some good humic will be more of an upfront costs...but the ingredients will last you a million times longer than the bottle of Liquid karma. Will give better results (can't beat freshly made kelp tea!), and give you better control of what you give your plants.
I wouldn't recommend that as Nirvana has azomite in it and azomite tends to burn leaves, (so I've heard). I really think Nirvana, (great stuff by the way), is best as a soil drench.
