Yellow Edges on Newer Clones, Advice Please?

I just came into 3 Clones about a week ago, but now two of the three seem to be experiencing slight problems. They are two separate strains, one mid level indica and a super skunky sativa. The indica is around 5 inches tall, but is very lush. It has yellowing around the edges on about a quarter of the leaves. The yellowing is not crispy or dead yet, but it is very new and i am concerned this is the direction it is heading. On the sativa, it has a few dark orange spots on the upper leaves. The first four pictures are the Indica, the last two are the sativa.

I am wondering what is causing this and how i should fix it. I am have four 150 watt cfls in a box that is five feet tall by six feet wide (obviously for later flowering) I am not sure when the plants went into vegetative growth, but they have been topped once or twice and are around 6-7 inches tall. Other than the spots or yellowing they look very healthy, very lush. I am using fox farm Grow Big for vegetative (6-4-4) and i am using Fox Farm Big Bloom (.01-.3,.7) for flowering.

Hopefully that is enough info for a good diagnosis, I really appreciate anyone that could help. I know that people get mad when newbies post stuff like this but i looked for a while and i couldn't find anything that really identified my problem or helped. Thanks!!

P.S.

Does anyone have suggestions when these things start to smell i l have them in a 18'LX10WX8'H. Filters?

nitrogen def. maybe

what you need to do is get a fox farm feeding chart and follow that, you will see that for veg they recomend grow big and bloom and tiger bloom i had the same problem when i was using fox farm and that was the cure i guess that its not a one part fertalizer and you have been using it like it is so thats where your defiency problems are coming from

they will start to smell once they have been vegging for a few weeks but it will probably be more of a plant smell as opposed to fresh bud smell that will start to reek when they start to flower
