    Runoff ph and re-using a fabric pot

    Hello everybody. Had a question about testing ph runoff. I'm growing a Mephisto CDLCxSkywalker in a previously used fabric pot with fox farm ocean forest and fox farm trio of nutes. My ph runoff the last few feedings has been about 1.0 lower than what I put in. This is my first indoor grow that I've tested runoff on and I'm not sure if it's normal or not. The pot was used last season for an autoflower I grew indoors also with the same set up. Stuff I've read on testing runoff doesn't mention if a used container could cause skewed numbers. Didn't know if anybody had some insight. Thanks for reading and happy growing.

    DID YOU WASH THEM!? DID YOU SANITIZE THE SPACE??!! ............I'm sorry for shouting really and I apologize if I err! Temp vacant tents can be a breeding site for many nasties, pots too especially! All breeding sites for nothing you want!

      A 1% diff in runoff from input is not bad at all. I understand that input for soil should be 6.0 to 6.9. None the less you have a lady to be proud of so flaunt her all you want, we love it!
