from the first pic, id say you're either manhandling the buds and its resulting in the hairs turning brownish/orange (happened to some of my friends plants due to ppl touching the tops) or it could be the CFLs are too close - i keep a mom in veg under 6 CFLs in my bathroom and theyve gotten burnt a lil before from being too close. as for the second question, dont expect them to get too big considering youre flowering w/ CFLs.

after looking at the first 2 pics again, im pretty sure theyre changing color due to being touched/mildly burned. just make sure not to let anything touch the tops and theyll be okay. also move the CFLs back until the heat isnt noticable near the plant. other than that, you're good to finish & smoke up!
