it would help if you could put up some better pics, though i can see the leaf troubles that you're talking about
plant is pretty stretchy, looks like growing outside?
i can see two sets of lower leaves have the same spots, this could be a problem, might fix itself but more than likely it will move up
pot looks large, could well be nute lock of some kind
what ya using for soil/water?

Im usising happy frog poting soil, cut with 30% by wieght of washed sand. Right now im watering about 10-12 oz of filtered water every 2 days, depending upon temps. I recently moved the plant into a grow box and it seems to be responding to the 24 hours of light its getting. Ill work on posting better pics in the next day or so. Also i just topped the plant (about a day after the pics) to see if i could get it to bush out a bit. the leaves are looking quite a bit darker than they were and its still growing fairly quick, about 1 inch for every 24 hours of light, keep in mind that im still using floros, ill be switching to one 50w mh and one 50w hps in about 2 weeks, just waiting on the money to do it.
 
nute burn.just flush with ph'ed water till she starts looking better then come back with 1/4 the strength in nutes and work up
 
I am also getting brown spots on leaves as well... I posted this in another section, maybe the answers we get can help?

I have included pictures of the setup / I cannot tell if it is a slight nute burn because it is the middle of the leaves on one or two that have become a light brown and spotty (only one leaf has a single browned tip on a different plant). The ppm in the solution is 191 after just measuring it and have better ventilation (no fanning was on it before or barely) which could explain the burning in the first place. Temp picture and humidity included as well (generally is in 40's with door closed.) and temp was higher in the 80's before and managed to cool it down over a few hours and different rigging. It probably is just light burn, but I am hoping for more opinions and really am not wanting to kill them since it is my first grow!!! There is a solution of flora grow series + B vitamin and they all 1/4 of the normal seedling dosage per gallon (w/ exception to the B vitamin which recieved 1/2 normal dose per gallon)... HELLPPPPP!!! :smile:

(update, temp is now down to 70-75 and added a half gallon more water to dilute the nutrient solution)

also, they are each 8-10" away from 4 x 100 W CFL lights if that helps

Sounds like you're making progress. The darkening of the leaves sounds better. I've never used happy frog, that's an organic soil? Someone mentioned nute burn, but I don't think you mentioned you were feeding any nutes. I'm just guessing, but your soil shouldn't burn, especially with 30% sand.

Ok here are a couple pics with a slightly better camera.

worm,
You should open a new thread under plant problems, really shouldn't post to someone else's thread. I know it can be frustrating getting help sometimes. Your cfl's are too far away though. No further than 5 inches, 2 inches pretty close to optimum.

nope, not feeding, the guy that gave me the plant said i souldnt feed till 2 weeks before flowering with this soil, and yes it is an organic soil, the ph of the soil runs between 5.8 and 6.5, im guessing cause the sand and soil may not be mixed well enough, i get slightly different reading depending on where i take the sample.

From your pics, things look better. I'm not a seasoned pro, but for the moment I'd say keep doing what you're doing. Some weak nutes probably wouldn't hurt. For example a little fish emulsion, manure tea, or whatever you're planning on using. Just make it dilute.

its doing great now, once i got it some better lighting 2x 70watt mh light with dimpled reflectors, and topped it, its really taking off and is looking nice and healthy. im guessing i just didnt have enouhg lighitng for how strong the soil was.
 
some one asked for a new pic of the plant, well here are a few. for more pics and to follow what im doing check out my grow journal. its called thai strain grow.

A little sparse, but much better than it was. Though it it's a thai sativa, I think they have a thin look to them. Congrats on recovering your grow. I +rep anyone that can recover a grow.
