First time growing here. Things were going well for a while but now the plant is starting to look bad. I’m not sure what’s going wrong, I couldn’t find a clear answer online.

Should I just harvest now and hope for the best? Or is there a way to know when it’s actually ready? I don’t want the plant to die before I get a chance to harvest it.

Random seed I got from a friend, don’t know the strain. Is nonautoflower. 10 weeks old 3 weeks since 12/12 light cycle. Been flushing last week.
