My PPM maxxes out anywhere from 1400-1700 around week 4-5 till week 7 on an 8 week strain..
With good genetics and and keeping in mind that all strains like to be feed differently play with these things..
If u have a particularly frosty resin producing strain dont be shy to hit them with a good cal-mag or similar nute to max them during peek flower time. U wont be sorry.
Ya, I guess tonight I'm going to add H2O to 8 gals and raise the PPM to 750 and take pics and what for nute burn and see if they just soak up the H2O or hopefully they will soak up some nutes so I know they are not nute locked. Thanks again SMILE
