Looking for some help/general opinions on my cab grow

Hello all, this is my first grow and i pretty much learned everything i know from these forums and faqs so thanks for that. I have 8 23w CFLS, 4 daylight 4 soft. Im not exactly sure on the genetics of the plants but i know they are sativa dominant.

The first pic is of the cab/lights/plants. You can barely make out a PC fan on the upper right, I have an exhaust and an intake fan and the temp is perfect (had only 4 bulbs and no fans yet when they were seedlings and holy crap did those 2 PC fans make a huge difference in the temp)

The 2nd and 3rd pics are the plant that is worrying me a bit. The new fan leaves are super thin and the old ones are dieing. I know you see a bit of yellow in the rest of the plants, but im about 99% sure that was just because i waited too long to nute them. None of the other ones have such thin leaves. Any ideas/suggestions would be greatly appreciated.

Thanks in advance!

If you are going to flower in there then do it now, you will have to tie them down and/or top them to prevent growing into light. I would rather say the burning leaves are from too much nutes. How much do you add? How often do you water your plants?

The leaves started yellowing and such before i ever even started nutes. But low and behold, i woke up this morning and its looking way better! so i think it was deficiency. Im going to start flowering today or tomorrow probably, just gotta go pick up a timer. Thanks.

if alls working now then great, maybe it was an overwatering issue, theres so little cases of under nuting causing burnt leaves that i dont think it was that

really? hmm...well there is one other possability, i was visiting family over break and didnt get to water them for a couple days, when i made it back they were bone dry and super droopy. Could that have done it? Like i said, and you can see, any of the new growth is nice and green, no yellow.

Any opinions on the 8cfls? I know its obviously not the best light, but sufficient for a decent yield?

welcome to the forum. Please get Garden Knowm's book. See More Buds - Grow Marijuana DVD The author tells how he grew 8oz of bud using 8-42 watt cfl's from 3 female plants. Your lights need to be placed better for maximum yeilds. Great start, constant improvement is your goal now. VV
