if i were you, id be doing just what you are.

Hi everyone

Oau! This has been an interesting debate! Many thanks for all your input, it was really very helpfull and good things have come out of it. As for me I finally understood how that calculator works and what I should be aiming for when I fertilise. I finally know what "weak" means. What is even better I can now always calculate for myself how much I need to use from the label on the botle.

This morning I watered and fertilised both my phals with 100 PPM N (if they are ok with that will increase next time).
I used the Bloom one for the phal with flowers (3 ml of fertiliser in 500 ml water)
I used the Grow one for the small recovering phal with one root ( 2.2 ml fertiliser in 500 ml water).
