well i got my testers in the mail and decided to check my runoff i only did 1 plant and the runoff PH was at 5.1 ppms 1800 the soil is only a few weeks old and mixed by me should i be worried or will the soil act as a buffer? its promix,perlite,ewc and compost with a little bone meal and a touch of bloodmeal
Use some nice 8.5 high PH city hose water and it'll balance out. Too much hose water over to many years finally defeated even sulfur dust and I had to take stronger measures to pull the soil PH back down. Promix is Peat and the reason for the low PH.
If it already has a plant, you can sprinkle a bit of baking soda under the plant or use some soda PH adjusted water and push your next watering up to 8 PH.
It's pretty bad low 4s I may need to flush the medium but my readings could be because of buildup in the bottom of the pots I need to do a slurry test I guess but they look happy anyway
