So the other day I had mixed the nutes for my res and then filled the res ,I took an EC reading and it was perfect at 950 then the next day I took another reading same nutrient solution it went up to 3500 WTF , I cleaned the ec meter calibrated it several times to no avail. then I took it to local hydro and had them cali. it same thing so I bought a new one and damn it if it doesn't read the same so it turns out that it had been reading low since I have been using the res., I flushed everything then started over .I will have to come up with new recipes for the nutrient solution no wonder I had 2 plants wilt up and die
