Nutrient Burn OR Plant isnt WELL

Looks normal still. Autoflowers often take longer than what the manufacturer states. Just have a bit of patience, she will pick up. For mine, it usually starts from day 60+ until they get nice and dense. Don't worry, even if the leaves turn a bit brown. If you're unsure, just measure the runoff; it should have a pH value between 5.8 and 6.5 and the EC value not over 2. Hope that helps you a bit!
