Fertilizer Question. Do what it says on the tin?

Hi All !! Okay I need to know if the feed I'm giving my kids is good enough ...
The product is Westland's Organic Tomato & Vegetable Liquid Feed
Usage 1 Capful per Gallon (4.5l)
ok ingredients say
E.C. Fertiliser 4:2:6 plus trace elements
Nitrogen (N) 4%
Phosphorus Pentoxide (P2 O5) 2%(0.9%P)
Potassium Oxide (K2O) 6%(4.9%K)

The numbers and letters inside the above 3 brackets are the chemical symbols

Is this any good?

Advise????

Hey dude... A gallon is NOT 4.5L, it is 3.8L. I just thought you should know, metric system... BAH!

L0rdsOth :D

Er..., I think 4.5l is an imperial gallon.That fert could work for veg cycle, but no good for flowering

duh! i'm not arguing how much a gallon is dudes !!!!!!!!! i wanna now about the feed i'm using

that is week for vegetation but it will work. It's not the correct nutrients for flower, fyi
