Hi growers I think this is a disease in the plant because I've another strain in the grow doing fine.
Is it beetroot lettuce so something sounding like that? In coco ec runoff all good
It looks like you are having some major pH and nitrogen issues here. I would flush with pH stable water at 6.3. See if she bounces back after that. You will notice after a few days. Cut back on your nitrogen feeding.
Hope this helps.
