ok so i been growing in coco coir for years, using hand watering in pots. i just started some 100% perlite hempy buckets
all goes well except now the plants looks nute deficiant, im useing the lucas formula i flushed and fed and the nutes are were thay should be and so is the PH, i put it in at 5.8
but it seems the PH rises back up or something because im having nute lock out for shur,
im using tap water around 200 ppm 7.6 PH out of the tap
i used the same ferts and water for my coco grows and it was fine
all i can think is that since the coco buffered the medium that the PH never drifted back up, and now im useing only perlite so the there is no buffe rand the PH just rises back up after i set it.
i asume carbonate hardness is the cause.
anyone know if useing GH for hard water will keep the tap water from rebounding back up in PH
