    Hello All,

    Hope you can help me with a problem I'm having with the EC. I am in the 3rd week of bloom, plants have started heading on time for the last week.


    Have EC set at 1.8 and Ph 6.1

    Growing room with 1000w

    Avg temp 27-29 cel

    Medium - clay balls & perlite

    Running pump watering system, feeding 30 minutes, 5 times daily

    For some reason my EC raises almost after every feed. If left without adding water to tub for a day or two, EC goes from 1.8 to as high as 2.5.

    Thanks for your feedback everyone. :)

    Sounds like your plants are taking up water and somehow not as much nutrient. The water is being used, but the nutrient is left behind, somehow, giving you a higher concentration in the remaining solution than you want. Maybe try adding a little less nutrient to your water. Watch the plants overall to see that they maintain the good shade of green you most likely have. Overfertilizing is always a good place to look for problems.
    Also sounds like your room temp and ph might be a shade high.
