Yes ph is one of those things that can be confusing. Sometimes I wonder if I just need to throw away my tester, since I am using living soil. When using bottled nutes I always made sure the ph was at a 6.
Now since I am using living soil, all the microbes and bacteria work and keep the ph at the desired level. What kind of soil and nutes are you using?
to be honest, just potting soil and sowing and cutting soil I don't know anymore. The packaging said it was also good for edible crops
You probably could use some fertilizer with a high phosphorus in flower, since most souls are good for veg. What is the brand name?
