Ray , i took two readings one being 422 ppm other was 660 microsiemens .
To finish, i think what has put me off thinking the readings are wrong
somehow is that the TDS is higher than i thought it would be @ 125 ppm
N.
Especially at every watering .
i would normally peak @ approx 500ppm in summer then reduce ppm to a
low of 250ppm in winter .
I will stick to 0.75 -gallon and see what the results are !
I apologise if this has dragged on , but i needed to know what i was
doing is correct to the recommended dosage.
Cheers Keith
