Hi Deborah,

What an astute observation and a great question!

I'm assuming you are comparing Maxicrop Liquid Seaweed with Maxicrop Liquid Seaweed for Trees, Flowers, Fruits and Vegetables. I have found both those products on vendors' sites online, but I can find only one of those products (Maxicrop Liquid Seaweed) on the Maxicrop website. 

My guess -- and this is just a guess -- is that Maxicrop no longer produces the latter, perhaps because it was found to contain some trace ingredient such as a heavy metal that should not be ingested. Instead, the company appears to be marketing a different product, Maxicrop Liquid Fish, for use on food crops.

I did find safety data sheets for Liquid Seaweed and Liquid Fish, which I have attached. I could not find a current safety data sheet for Liquid Seaweed for Trees, Flowers, Fruits and Vegetables.

To make things even more confusing, I noticed that Liquid Seaweed is advertised on Maxicrop's U.S. website in the "farming and agriculture" section, yet it is clearly not labeled for use on food crops.

I'm sorry I can't definitely answer your question, but the company might be able to give you more insight. Its customer service number is<personal data hidden>.

I hope you can get more information from them!
