Brown and Yellow Shit On My Leaves!! HELP!!!

Ahh some one please tell me what's going wrong...the leaves have brown and yellow spotting on them and I'm not sure what is wrong. I figured it was nute brun so I eased up on the nutes and flushed it with freshwater but the spotting is just gettin worse....i water them every other day...they are on 18/6 light cycle...they are 3 1/2 weeks old...i use 5 100w cfl's and 4 75w tubed fluoros...the temp ranges from 75-85 F ...i take good care of them as best i can...whats up guys??

Looks like some inadequate lighting. The problems are only on the lower leaves right? And they seem to be drooping a bit which supports that theory.

Other option could be mirconutrients.

thinkin over watering and too much nutes while you water, seeing that the yellowing starts from the outside im guessing nute burn, you also might want some more lights too

That yellow is definately not nute burn. If it was the tops would be yellowing too. I'm still thinking light/micro. Do you know what your soil ph is at?

yeah i hear ya didnt realize that

i'll throw my .02 in. i see a lot of bark in that soil mix. Bark is very acidic. If I hadn't noticed that, I probably would have said overwatering by the looks of the droopy leaves, but that discoloration is a pretty unusual pattern. I'm going with pH.

You have a bad case of over watering going on right now...Slow down watering to 2 - 3 times a week...And remember if you were over nuting your plants there going to get worse before they get better as you flush them...

Here's a page you might wanna save for a reference. Show pics of some different deficiencies/burns & problems. But I would still not take any action if it were me before getting as many informed opinions as possible.
