last saturday i asked: what-does-she-want-to-eat https://www.rollitup.org/t/what-does-she-want-to-eat.833257/
then wednesday i asked: what does chlorine do to your plants? https://www.rollitup.org/t/new-dumb-question.834037/

today i ask what do you think is going on and what should i do next?
to me the plants look way better but the ppms keep going up... that seems wrong but i am adding the ph up everyday. so what do you guys think

that's not a large increase. top off with fresh water daily, change the res weekly. what brand of nutes are you using? what is your fresh water tds?

get your res temp down to 65-70. otherwise you're asking for pythium.

Sounds like your issues is caused by not using a constant supply of the same type of water. Save yourself a bunch of headaches, get an RO machine on ebay or something I picked up a 400GPD for like $300, you can get smaller ones for cheaper. The RO that comes out is 40PPM. Once you do lucas formula to that, theres no need to even mess with the PH because it's gonna be right where it should be around 5.7-5.9 after adding the nutes (unless you're not using GH)?
