Well when lights came on next day, those balls increased in size and started to drop downwards, I decided to not risk compromising the others, I'm very pleased with 7 fem anyways. Also due to smell and small apartment can't afford any other place where to put it so it is gone now. Thanks for the help guys.
I donno what to do with the orphan dripper now. Is it ok to leave it in the empty pot? I'm running a wilma system with canna coco and clay pebbles. I worry pebbles and coco absorb the food from the others, or it doesn't matter? What do you think?
