Sherb biker hunt

So this week I've had to kill 2 plants both were males .... only 1 plant is showing as female so far the other two ain't showing nothing yet .... I'm going to pot up this weekend after a few more days of waiting to see the sex if I get one female I have faith it's gna be a good one from karmas history ...... they've responded well to the training and undercut defoliation they've had just outgrown there pots a bit now so transplant is needed .... upped the nutes this week 3ml a and b per litre while the cal mag stays the same ... thinking of adding a silica product into the mix has anyone got any experience with silica ? All in all plants are healthy and thriving fingers crossed my single fem is a beauty ..... happy growing
