I just took samples from the root area of my remaining plant to check pH, as I’ve had a lot of problems with it. The pH was fine for all three samples, but I did notice that my PPM was <300 for all 3 samples. Should the PPM from the slurry test = your desired PPM?
The ppm being so low is an indication that they are hungry. How long ago did you feed them?
The slurry test is for more accurate pH. Not so much for ppms/tds.
Fed to 900 PPM runoff 3 days ago.
I’ve used the slurry test for ph and to check my ppm. What is your feed/water schedule. I feed then water and repeat. If I was going into a water day at 300ppm I’d be concerned. I may feed again at a little higher rate then come back with a water. I feed or water about every third day with this group of plants.
It’s fine for ppms, you just have to wait 12+ hours for a good reading.
Cool. I still have my samples.
