Soil is FFOF. Feeding ph 6.5-6.7 with 1200ppm and runoff is around 5.8 ph
With your ph going in at 6.5 and comming out at 5.8 I would bet your ph in the soil is pretty low. The low ph is going to cause lock out issues which will in turn cause random nutrient problems. You may not have been over feeding by much but over time it adds up. Any idea what your ppm comes out at? Or do a slurry test to get more accurate results.
I'm thinking of doing the same thing. Being able to adjust the medium ph easily sounds kinda nice!
Yeah I found out that happy frog soil ph starts to get really low and is impossible to correct with ph up. Now I'm doing coco indoors and the ph is perfect . Soil will be outside only now, and use up the rest of my old bottles soil nutes out there
I have the same issues with Sunshine mix. Ph just drops after all the lime is used up. Not sure what your water source is but I switched over to a 50/50 mix of ro and tap. Im thinking the combo will lengthen the buffering ability. Seems to be working good so far just hit day 100 in veg and ph is still stable at 6.3. Oh yeah and I really try not to over feed.
after trying a slurry vs my ph pen I would say the slurry/runoff methods are very inaccurate. It was totally worth it
I'm gonna have to get me a pen then. I always heard mixed reviews on soil ph testers. You have the bluelab?
Just checked that damn meters $250 wth!...not that I wont buy it but man this is an expensive hobby.
