chops,
nitrogen is a macro nutrient available in most fertilizers. typically a fertilizer will have a 3 digit ratio of macro nutrients (N)itrogen, (P)hosporous, and Potassium(K) in that order N-P-K, typically a veg nutrient will have a larger amount of N than P i.e. 7-4-10, a bloom will have more P and less N i.e. 4-8-7.
Since you are in flowering you should use a bloom fertilizer which should have enough N to prevent chlorosis.
I would also hit that plant up with a little Magnesium(Mg), available in epsom salts, probably a 1/4tsp/gal would do the trick.

looks more like radiant heat damage, what are your temps and do you have fans circulating air in the growing area?
Well temp has gone up to 90f and i have an air cooled light drawing the air out of the cupboard and have a fan circulating the plants too 90f isnt that bad is it.... well i gave them a flush today just incase anymore opinons much appreciated and thanks to all that have poasted already

chops,
if your heat is reasonable, it seems as if Mg deficiency is the most likely culprit.

Although it looks as if you may be able to solve this with a reduction in temperature.
