Ok. What are the temps in the flower room? Is there adequate air flowing over the plants? Yellowing leaves is normal towards the end of flower (more in some strains then others)and if you continued with N during mid/late flower the leafyness is what results from that. The dark necrotic spots sounds like a late mold or mildew. Any cottony looking whiteness on the leaves or buds? Are the spots like a greyish blue? Any visible signs of pests(ie-Slime/honeydew egg sacks gnawed upon leaves or the bugs themselves)?

YE, THERE IS LOADS OF AIRFLOW, I HAVE CHECKED THESE THINGS, BUT IT DOESNT APPEAR TO BE,any of them, there isnt any sign of mold, no smell, its very odd, ill get the cam back asap

Do the spots look like rust kind of? If so, you have what's known as rust spots. I sometimes get them on my plants towards the end of the budding cycle. Don't ask me how and where they come from, but i know they are a fungi. I use a copper spray that kills those fuckers. If it this, they have safe sprays you can use almost up to harvest. It also could be heats spots from the lights. Even if it feels cool to the back side of your hand. You can still have heat spots on the leaves. I hope this helps you, and a picture would also help us with your problem. If you got a camera to take a picture.
Good Luck

just to say, the leaves with the spots on have all fallen off, with the normal yellowing now, turning the lamp off in 9 days, cutting after 24 hours in the dark, no more spots have appeared, so i think we're ok, thanx though guys.

Sorry if it's boring...

Potassium deficiency:
Older leaves are initially chlorotic but soon develop dark necrotic lesions
(dead tissue). First apparent on the tips and margins of the leaves. Stem and branches may become weak and easily broken, the plant may also stretch. The plant will become susceptible to disease and toxicity. In addition to appearing to look like iron deficiency, the tips of the leaves curl and the edges burn and die.
Potassium - Too much sodium (Na) displaces K, causing a K deficiency. Sources of high salinity are: baking soda (sodium bicarbonate "pH-up"), too much manure, and the use of water-softening filters (which should not be used). If the problem is Na, flush the soil. K can get locked up from too much Ca or ammonium nitrogen, and possibly cold weather.

Phosphorus (P) deficiency:
Figure 11 is severe phosphorus (P) deficiency during flowering. Fan leaves are dark green or red/purple, and may turn yellow. Leaves may curl under, go brown and die. Small-formed buds are another main symptom.
Phosphorus deficiencies exhibit slow growing, weak and stunted plants with dark green or purple pigmentation in older leaves and stems.
Some deficiency during flowering is normal, but too much shouldn't be tolerated. Red petioles and stems are a normal, genetic characteristic for many varieties, plus it can also be a co-symptom of N, K, and Mg-deficiencies, so red stems are not a foolproof sign of P-deficiency. Too much P can lead to iron deficiency.
Purpling: accumulation of anthocyanin pigments; causes an overall dark green color with a purple, red, or blue tint, and is the common sign of phosphate deficiency. Some plant species and varieties respond to phosphate deficiency by yellowing instead of purpling. Purpling is natural to some healthy ornamentals.
