if you have a male, just pull the whole pot out and try to kind of "work" the as much of the roots out as possible
if you leave a few dead ones in there its no big deal as you should be flushing everyonce in a while anyway.
Looks great man, check those nodes every time you go near the plants, often times the bigger ones turn out male, so look for those balls and kill em early!
FYI, your "runt vrs healthy platns" is exactly why you never run this type of set up except with clones off the same plant.
one res per pheno is best
