Its so hard to say without pics dude, but here is something that might help you identify the problem. If you are using cfls, then its not the light causing the problem unless your light has a shitty spectrum, so look into light spectrums. As far as distance, as long as your light is between 1"-6" from the plant, it doesnt sound like thats the problem. Otherwise hopefully this list can help you identify the problem and you can find an answer:

NITROGEN (N) Pale plants, red stems, smaller growth. Rapid yellowing of lower leaves progressing up the plant. Add any chemical fertilizer containing N. Treated plants recover in about a week.

PHOSPHORUS (P) Slow or stunted growth, red stems. Smaller leaves that are dark green. Lower leaves yellow and die. Add chemical fertilizer containing P. Affected leaves will not show recovery but new growth will apear normal.

POTASSIUM (K) Affected plants are usually tallest and appear to be most vigorous. Necrotic spots form on lower leaves. Red stems. Leaves appear pale or yellow. Add chemical fertilizer containing K.

CALCIUM (Ca) Lack of calcium in the soil results in the soil becoming too acid. This leads to Mg or Fe deficiency or very slow stunted growth. Treat by foliar feeding with one teaspoon of dolomatic lime per quart of water until condition improves.

SULFER (S) Plants suffering from S definciencies exhibit yellowing of new growth. Mix one tablespoon of Epsom salts per gallon of water until condition improves.

MAGNESIUM (Mg) Lower leaves yellow and may even turn white while veins remain dark green. Blades die and curl upward.

IRON (Fe) Leaves on growing shoots turn pale and veins remain dark green. pH imbalances make iron insoluble. Foliar feed with chemical fertilizer containing Fe or rusty water.

MANGANESE (Mn) Necrotic and yellow spots form on top leaves. Mn deficiency occurs when large amounts of Mg are present in the soil. Foliar feed with any chemical fertilizer containing Mn.

BORON (B) Growing shoots turn grey or die. Growing shoots appear burnt. Treat with one teaspoon of Boric acid (sold as eyewash) per gallon of water.

MOLYBDENUM (Mb) Yellowing of middle leaves. Foliar feed with chemical fertilizer containing Mb.

ZINC (Zn) White areas form at leaf tips and between veins. Occurs in alkaline soils. Zn deficiency can be treated by burying galvanized nails in the soil. Chemical fertilizer containing Zn can also be used.

OVER FERTILIZATION Causes leaf tips to appear yellow or burnt. To correct soil should be flushed with three gallons of water per one gallon of soil.

Any help with the leafs i dont no what im doin wrong :L Everything else seems to be fine but theres a few tiny flys in my tent ??? HELP LADS!!

Cmon lads its getting worse !!

I have some Northern Lights. The leaf tips where the inner half is good and the outer half has a sharp fold aimed down and dried out? I get that all the time where my fan leaves stick out and hit fluorescent tubes. Otherwise?

I keep my temps in the 80's, the numbers are 83 to 86, I have tight venting. Humidity in uncontrolled, it was under 20 RH for the last two months, right now the meter is reading 16%. Summertime will give me 30%. It doesn't seem to hurt, and not a lot I can do about it.

Those little flies, hope they are not fungus gnats. I had a few of them, then a few more. Pretty soon I was breathing them, all the predators left for the winter and the fungus gnats were in gnat heaven.

Azatrol, twice in seven days. I am amazed, it really worked. Lower leaves quit being so yellow and sickly. The maggots really munch down on the roots.

I like that chart CourageToGrow posted, I always blame everything on light, good to have a reference.
