Good trick in growing period is adding cal-mag + humic acid. Grows vigorously without any NPK value. Also good overall advice on nutrients is to start like 1/3 of the dose what bottle says. It's easier to give more than start to flush overfed plants. Happy growing! hope this helps somehow👍

Hi I use general hydroponics test kit ph up and ph down not to pricey like 18bucks and it will show you where you sit ph wise ,it is fairly accurate and will last for many grows to come ...I'm always using more ph up then the ph down and it helps tremendously gotta hit that sweet spot or else your gonna get bite problems.. cheers
