I did lower nutrition after 1st res change - ppm to 410, that’s when this one started showing weird leafs - wilted toward center. Added cal mag due to brown spots. Have 3 others that really looked weak- so added some b12 and rhino skin per suggestion. Was following feeding schedule of fox farm for rest. According to fox farm supposed to use sledgehammer weekly with rdwc
