PersasHstarted grow question 5y ago
I ve performed several EC readings in water comming off my pot when I water and they always give very high values: 3.5 to 4.5. People told me it shoudnt be higher than 2.5. I ve tried two different substrates, last one biobizzallmix and very litle to non fertilization. Cause??

Calibration solution should be one of your tools as well. Once a month you pour a little solution into a clean container, put you reader in and let it sit for 5 min. Then adjust to the ec of the calibration solution. Your plants dont look over ferted, but it's nice to know you tds reader is right on. Happy growing friend

i would guess it's the callibration of your EC meter. I think the 3.5-4.5 range would cause some major issues well above and beyond anything i see in your recent week of diary. some yellow at bottom? perfectly normal in many cases in flowering period.
check instructions for callibrating it, if possible. find something with a known EC and measure it (RO water would be very low from a good RO system), if you can't callibrate.

White mold?My smart pot is turning white at the bottom. There also appears to be roots trying to pop through. I put rocks between the pot and plate for air. I have one blade of grass and a tiny weed popping up, so conditions at the top of the pot are okay. Should be worried?

Lightening Soil - Coco Coir or Perlite?I think my soil is a bit heavy and could have better drainage. Should I add more perlite or some coco coir for my next garden? My base is Biobizz Light-Mix. I'm thinking of supplementing it with 10%-15% of perlite or coco coir. Does this sound good or should I do something else?Week 10

First time testing PPM and slightly panicked :cRunoff was at 2200PPM. I flushed her with 5L of pH 5.8 water. I got the runoff to 1000PPM where I left it. The pH was at 7 though and was higher than before the flush. Why is that? I always pH before watering. Also, is the flush going to cause trouble for her? I kind of panicked.5y ago
