Water quality for hydro

Hi folks,

 

I need some advice about water quality in hydro. My tap water varies between 0.67EC and 1.0 EC. In the winter months it is lower. I made a water analysis in late summer when the EC was 0.9:

PH: 7.02
conductivity: 901 μS/cm
sulfate: 111
mg/L
nitrate: 25,1
mg/L
nitrite: 0,47
mg/L
NH: <0,05
mg/L
KOI : <0,5
mg/L
all hardness: 210 CaO
mg/L
m-alkalinity: 5,17 mmol/L
chloride: 54,8
mg/L
phosphate: 0,06
mg/L
calcium: 91,6
mg/L
iron: 7,9
μg/L
potassium: 2,76
mg/L
magnesium: 34,8
mg/L
manganese: 3,4 μg/L
sodium: 28,1 mg/L

 

When i measure the PH it is higher. Out of the tap it is 7.3-7.4, but if i leave it stand it goes higher 8.0-8.5. I need a lot of PH down, double the amount which is written on the back of the bottle. Usually 0.6-0.8 ml/l.

I tried mixing tap water with various amount RO water, but with no success.

 

Next round i want to try the NFT.

 

Can you give me advice on water and nutes? I mean what kind of water source should i use. Tap water with hard water nutes, or RO water with CalMag and soft water nutes.

What is your opinion?

NFT is the best system going mate. The gt205 versions produce insane plants.

I say try hard water nutes with your tap water first on a small scale and see If it works. 

Dutch pro do hard and soft water versions. Bit expensive but an amazing line.
