over-powered nute causing an Mg deficiency. Drop your ppm between 500 - 700. I run my neut based on ppm. I let your tap water sit for a few days. Cal-Mag your source water to about 250 ppm, fert that mix to around 600 ppm. pH adjuster will raise you ppm but still shouldn't be above 800. Now just sit back and wait on new growth.
