What could be causing this? Could it be low humidity First time growing in winter and humidity is super low around 30 percent. Added a humidifier. Showing Signs of Cal/Mag deficiency as well. First time Using Coast of Maine Platinum growers mix as well. Lights are dialed on lowest setting. Never seen this one before in my limited experience. Any input appreciated thanks!

pH of the soil could be off, and I don't see any cal mag deficiency, that would be at the bottom leaves. My quess like the rest, humidity. what's your temps with lights on and do you have air circulation going? fans?
