SICK PLANTS! please help

[groworganic]

I have some sick plants on my hands and I just don't know what to do. If anyone can help, I would greatly appreciate it. They are about two months into vegging under two CFL'S and they are all growing in soil. I am using Iguana Grow nutrients about once for every 3 waterings and following instructions closely. For some reason the leaves are turning brown and crispy and I am starting to panic...please help! Here are some pics to help you guys determine what it could be. Thanks.

IMHO,It looks like nute burn to me.So,this is what "I" would do.Stop with the nutes you are giving(for now) and give your plants a good flushing.Then see how things are in acouple days.Hope this helps.Keep it GREEN:hubba:
