Most cost effective way to get water? (GB)

[NaZzAtAzEr]

Back with more fertiliser questions.

I currently have "Formulex" for my semi hydro plants, a well balanced nutrient solution. I am struggling to get a good outcome on Rays calculator.

2.3:0.9:3.4

I have also purchased a calmag which is 6-0-0, 5Ca 12Mg.

Probably making life very difficult for myself!

Fertilizer PPM Calculator

Mine looks like this, although I still have to learn what it means! LOL

Algoflash engrais Orchidees (engrais =fertilizer in Francais)
NPK 3.4.5 with trace elements. 5 ml / Liter
ppm N 180
ppm P 105
ppm K 249

Cowabunga!

Akerne's RAIN MIX® in Belgium
RAIN MIX(R) - all seasons orchid fertiliser
recommended dosage of ½ gram per litre for each watering.
11.8N+2.7P2O5+13.7K2O+11.8CaO+3.5MgO+4.8SO3
ppm N 59
ppm P 6
ppm K 57
.5 g / Litre per week for 140 g @ €5.66 = 280 weeks @ €.02 per week
5.38 years

Edit:
Ray - I have found that applying a solution containing 75-125 ppm nitrogen per week is a great level to sustain growth and blooming.

So...
.85 gram/liter of Rain Mix
ppm N 100 right in the middle!
ppm P 10
ppm K 97
