The P H gos up to 13.25 + over night I have plants in clear water for now, they are 4 1/4 weeks into flower, cleaning the bucket system just got new nutrients there B C might not be the best but have had good luck with for 4 years could the new nutrients be the problem here, or something else,, could they be old from the store? my tester is a EW-35630-02 Oakton® pH/Con 10 pH/ Conductivity/Temperature Meters and have not had any problem with in the passed it was reworked 2 Mo. ago one bucket system is runing good it has the old nutrients in it yet, and the other sucks any ideas?

Hi lite
If you have checked the meter with tap water and get a good reading there, the meter is working . Have you leached out the roots? Sometimes salts and nutrients build up in a root mass. there's alot of products for that purpose. Best of luck to you , hope this helps
peace

Have you recalibrated your meter lately?That could be a problem if you havent done so for some time.
