LMAO! All I could think was "awwww... look at that little Princess!" ... she stole my heart!!!
You'll find that every once in a while, along comes a seed that just doesn't behave like her sisters do... I'd put it down to genetics, myself. Still in all, I'm wondering if she wouldn't benefit from some ReCharge which really gets the root system going... does she go through as much water as her sisters? If not, you might try it... it's great stuff anyway and I've now incorporated it into ALL my grows from the get-go...
Good luck!
