The poor through test .

[Masdyman]

I have been reading a article about feed(i think Atlantis orchid society ),ph etc it goes on about a pour through test to test the medium in which the orchid grows ,by which you feed your orchid ,leave it for 30 mins then pour 2 oz of distilled water through the pot .This water you then test the ph & EC , if the EC reading is less than 1 ms/cm which is 1000ms right ?then this is a sign the orchid isn't getting enough feed,Then you can feed at a higher strength for a while to get the EC higher in the medium .
If you feed at 125 ppm N then they recommend the EC should be between approx 1.5 -2.5ms/cm this seems high to me .The medium PH should also be between 5.8-6.2 for the majority of orchids.
I did this test and here are my results
My RO = PH 6.5 /12 microsiemens
feed strength =PH 6.2/620microsiemens
poured through water result = PH 6.5/120microsiemens

What do you think of this test ? going by the advise in this article , i can increase my feed strength but for my Masdevallias don't want to feed any higher than 75 ppm N(approx 620ms) @every watering which i have been doing .
