It's hard to say really, I can't seem to find any information of the percentages of nutrients it contains but its contents include "iron, potassium and magnesium, ammonium, boron, copper, lithium, manganese, iodine, tin, nickel, cobalt and a few more ingredients to make this your complete plant fertiliser.
They've also included a fancy picture of the above listed chemicals on the front of the bottle.

The alarm bell for me is that they don't mention phosphate, which is a rather important nutrient, especially if the seller is labeling the product as " complete."
I could of course be wrong and maybe when they state "
a few more ingredients to make this your complete fertiliser," this actually means they've added phosphate and forgot to mention it 🤔
Obviously I don't know your set up, and it could well be the case that your tap water contains enough phosphate to feed the plants, I guess what I'm saying is try it and see how it goes.
Hope that helps👍
