Calcium and magnesium shortages turn up constantly under LED panels, partly because higher intensity raises demand and partly because filtered water supplies none. Rust coloured spots on middle leaves are the usual first sign, and the deficiency guide on https://kushindicaseeds.com separates that from a plain nitrogen issue. Coco makes it worse by binding calcium early on. A basic supplement from week one prevents most of the trouble.
