Some pictures would help as well as your general location and zone.

That fertilizer ratio is no good. Citrus need a lot of nitrogen. Try and get some foliage pro. If you can't get that, some people recommend the miracle grow for acid loving plants, I would only use that in a pinch or if you can't get foliage pro.. That ratio is 30-10-10. But be careful with it. Post a picture of your tree so some of the expert members can help out more! I'm still a novice, only been growing 2 years with citrus

i have been trying to put the photo i took this morning but it doesnt work. I might be doing something wrong, but i do not know what

Have you checked your pH? Have you taken a good look at the roots to see if they are healthy? Are your temps falling below 55 degrees often?

Keep trying the photos. Are the leaves uniformly green, or only in parts? Are the veins green?

Are you trying to upload the photos from your phone or a computer?
