Hello cptweedmanguy

I know the feeling, to say it's annoying is a understatement . The last couple of grows I've had mine drooping their fan leaves and the tips curling downwards like you describe and I havent a clue why
The only thing I can suggest is to work you're way through different things that might be causing a problem and try too eliminate possible causes like over or under watering, heat, cold, lights, and so on.

I wish I could say what might be the specific cause but ................ sorry



Goodluck ................................ love mand xxx
