I Thank you all!!!! You make this to a wonderful place.
@Waira
I have try you PH run-off test.
But i dont know if i have make it correct.
I set my Tab Water to 6,5 Ph with ph-. (without nutrients)
Give her very slow the Water so that every bit of Soil is Wet. Run off was 200ml.
Than i let it sit for an hour.
After that i give the her distilled Water. (i set her over a new clean saucer)
The run off Water have PH of 7,3 and ppm 1500
)
Soil PH is =7.3 + 0.8
Soil PH= 8.1?
Could this be right?
Should i give her a flush with ph 6.5 Water? or with my Tab water 7,6 Ph?
Sry, english is not my native language.

-- looks done right to me mate,... and your English is plenty good! ....the results make sense, even if it's a rough estimate...alkaline conditions will really lock-out micronutrients like Mn, Fe, Zn,etc.,.... So part of the question is how did it get that high,... tap at 7.6 hints a moderately hard (mineral content), what does the TDS say about it's ppm's? ... basically, the more minerals are dissolved in the water, the harder it is (this is a measure of how much CaCO3 is in there), and high content makes for high pH..... With pH buffering, it's the CO3 (carbonate anion) that's involved directly with pH buffering,.. maybe between the water and the Ca-Mg, it's accumulated enough to drive soil pH too high,... Also, too much Ca can start ti interfere with the uptake of other nutrients, and so might also be a factor here,... the run-off ppm's are high for sure, but the jump in ppm's during flush is odd,... Generally, a flush starts with 2-3x the pot volume of pH adjusted water,... pH set at 6.5 for your case,... I'm a little concerned about your pH meter Sirro, has it been calibrated in proper solution 7.0 recently? Is it stored in storage solution made for this? that glass electrode is a very delicate part! TDS meters can go out of calibration too, but far less easily,..... flushing needs to be done fast, like 20 max, or you risk suffocating the roots, and starting more troubles! 
-- and last pour should have about 1/4 strength nutes in there IF you've run the right amount of water through,... If you've done some already, then stop for now and let her dry out a bit,.... What were the results after you finished that last time?
