Things are looking pretty good so far, but I have a few questions:
1) Are you buying feminized seeds? The reason that I ask is that although some breeders seem to make reliable feminized seeds, others are notorious for making hermies. This may be the source of your problem.
2) Is the indoor mix a random mix of different strains? If so, you might find that you are overfeeding some and underfeeding others if you have them all hooked in to the same res.
3) Are you cloning? If so, I suppose you can keep them together and eliminate the feeding issue.
I see now that it looks like your other plants are in soil. Are you going hydro this time, or are you transplanting the rockwool into soil?
Oh, and it looks like you have a nice couple of rooms. I'll definitely be watching.
