Looks like its going nicely! Your clone rooted great, thats your first time? Nice work! Glad you got the temps wrangled under control too. Sounds like the plan is working. Now, hook me up with some of those NYCD clones!

In my experience I have found once a hermie, always a hermie. and if it is a hermie, just get rid of it (kinda like if you found out the girl you met last night at a bar has a dick). Not worth a shitload of hermied seeds in my next batch ya know, plus the headache/hassle of trying to remove em all. Thats why I pulled my AK48 a few weeks early . But if its only the one plant then you should be ok letting it finish.

And yes, I believe you can induce "hermification" by removing female flowers - anything that causes stress to the plant. Hermaphroditism seems to be a survival mechanism. Can you take some good pics of one before you rip it off next time?

Yellowing in the older growth is (somewhat) normal, and it doesn't look too extensive in your case. Looks like its a little light atrophied as well, which happens to the lower shaded branches. Just make sure you N her up next time you feed, or foiliar feed some N (if not flowering) and she'll be fine. Splashing concentrated fertilizer on her is not a good idea I like to swap my mothers out every 6-8 months or so, with the healthiest clone of the then current batch. Then you can either flower the 6 month old mommy in the chamber, or (as I'm gonna try this year) just put the old mommy outside and let her rip.

Looks like you are doing good - next time you take pics, take some out of the closet with normal lighting and show off them buds!
