No, perlite is inert. I grow in peat and perlite media. It also has lime and gypsum to to neutralize the acid in the peat and provide a stable pH. Maybe you should try an inert/soilless media? Get a name brand media that is recommended for cannabis, and quality nutes. Make sure you are using suitable water.lights?
does perlite change the ph of soil?
