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!

You will need to use the fertilizer and the calmag at separate waterings, and not mix them together, to avoid precipitation problems.

Put the nitrogen number 2.3 from your fertilizer into the calculator at First Ray's. It will tell you how much of your fertilizer to add to water to get the desired concentration. People use low levels for fertilizing at every watering, and higher levels if watering at longer intervals. I believe Ray suggests about 75-100 parts per million of nitrogen for use at each watering. His site discusses common concentrations used at different intervals.

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

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
