are these orchid fertilizers good?

[karrolhk]

I would get Better-gro if I could, but I am not in the US and dont have Amazon locally.

Locally, I could only find orchid fertilizers in the following NPK ratios:

for general growth - NPK 1:2:1
for blooming - NPK 2:1:3.5

Attached is a pic of the fertilizer I could find locally.

My question is, are these ratios good? The brand doesnt matter as long as the ratio is right, right?
