my marijuana flowers very slowly + yellowing leaves

I cannot resolve ths problem alone, even after reading problem related topics :(
My marijuana flowers very slowly + leaves started to yellow randomly on the plant.
Nutrient deficiency? I've added some fertilizer but didn't help much and don't want to kill the plant ....
Any help would be greatly appreciated.

Fairly norm during last few weeks flower.
How many weeks flower are you?
Sativa can take upto 12 weeks to finish.
What nutes you feed and ratio?
Soil using, lights, feed schedual all would help!
 
I think i'm at 8 week of flowering. Light is 400 hps.
Nut is vigoro all purpose plant food(N24,P8,K16). I don't know the ratio, i'm rather unexperienced glower ;/

You need a flowering nute! one with more P-K than N! eg 10-50-30, or 5-30-20. More P-K than N like double....you are using Veg nutes!
