Wow man, you have it all down to a science. If this were starwars i would say you just became a jedi knight. You know things now, after this is all said and done you will look back on your experience as one of the most educational interesting experiences you have ever had, and you will want more
Good luck with those clones, personally, i would say once you feel those roots are big enough, get them in something with nurients quick. Clones arent like seeds when it comes to nutes. The first feeding should be a slightly modified version of what you fed the plant when you took the cutting, Otherwis it will starve. The bottom leaves being yellow is a N deficiency. The newer leaves are using things like molbdenem(sp) calcium magnesium and nitrogen from the younger leaves, to make new ones. So like i said, plant them, water with slighty smaller amount of nutes, and everything will be a-ok for those clones.
Cant wait to see the college girls.
