Red,

I'm by no means an expert, but i would bet the roots on those two stressed plants are probably just sensitive to the nutes you use. Some girls are gluttons for feedings, and some will try to vacate the pots if you add 1/4 of the suggested strength. It could also be a ph problem.

Do you use the exact same mix for all your girls?

Very nice grow by the way, very ballsy for a 1st crop. I wish you the best. have you considered adding molasses to your feeding routine if you are already not using some? That should help feed your soil and plant at the same time.

i wish you happy yields!
