I feed all my plants with RO water and haven’t given them any additional nutrients. They’ve gone through a recent transplant from 2gal to 5gal on dec. 30. Just calibrated my ph meter and did a runoff test. The pics above has a ph runoff of 6.65 and a ppm of 1225. Temps stay around 68-72 and humidity hovers from 40 to 50%.
This girl has a runoff ph of 7.4 and ppm 523. I feel like this is off bc of the ppm reading and it being transplanted to a bigger pot on dec. 30. This is the first time I’ve gotten runoff from the 5gal pots. I think the RO water came out the sides without passing through the dirt and out the bottom. I would give it more water to get a better reading but I dont want to overwater it anymore as it got a bit droopy. Also both plants are 8 weeks old and are planted in FFOF soil.
Fresh FFOF should deliver TDS in the 2,300 to 3,000ppm range FYI.
Plants look good and you are doing just right by monitoring. No nutes til the plant tells you.
