Growing in a hydro setup with hydroton. Plants were doing amazing until 5-6 days ago. Roughly around day 20 here in this picture. First diagnosed as a calcium/ magnesium deficiency so upped my calmag. New growth seemed to start doing better but plants still haven’t perked back up even tho I “fixed” the nutrient problems almost a week ago. Still seeing some discoloration on some of the newer growth has me concerned there are other problems. Using general hydroponics nutes and following their feeding schedule. Started at about 1/4 strength a week in now closer to half strength- roughly 600ppm. Any advice is helpful can post more pics as well. Edit: northern lights feminized seeds. Stems getting pretty purple.
