Need Help!

I have 12 plants no older than 1 month, and the leaves are starting to get cruchy and turn upwards. This is my 3rd indoor grow, and i havnt had this problem befor. What is wrong with them and what can I do. I kno someone here can help me.

more info, pix?...overnuted or lightburned, as a guess

I cant get pix now. I dont have my camera. They are deff. not overnuted. I havnt been giving them nutes until yesterday when I realized that I had forgot to mix the nutes. They are about 4-6 in away from 4, 4ft floros., so i dont think they are getting burned. Its mostly on the lower bottom leaves. I forgot to mension that they are turning yellow and then brown.

are these clones or from seed

did you do exactly what you have always done on your 1st 2 grows?

they are from seed. i dont think i have differed much in this grow or my others, except these were started under cfl's and instead of pete pellets i used soil this time. what i thought the problem is, is that i havnt been giving nutes for a while. could that be the cause?

sorry, brother, there are so many things, without pic's, this one is kinda tough...
what nutes are you using, used or going to use?

Im just going to start from the begining. In my other grows, i used pete pellets to start my seedlings, and 4' floro's. This time I used soil instead of the pellets, and cfl's instead of the 4' floros. In my other grows I used the same nutes, but this time I didnt use the nutes up until yesterday. So they havnt had nutes for most of their short lifes. A few days ago, I noticed that a few leaves on different plants had began to discolor (yellowing, then turning brownish), curling upwards and becoming crunchy. I think that it is because of the lack of nutes, but I wanted to get a few other opinions.

usually, nutes aren't used on seedlings until they have rooted well. the lights are alright, but I would use my fluoro tubes w/cfl's on the side, because you cannot give them too much fluoro...anyway goodluck to you
