it was dark and raining yesterday. brought plant inside. put it under two new lights.. 2x 250w mh... guessing to much light or heat???
Hello friend! Can you take a few pictures of the entire plant..? Hard to tell but almost looks like some sort of chemical burn...
hope this helps...oh, now that u said that. acouple days ago I sprayed apple cider vinegar on it for powdery mildew
