gold speccles all over plants...

My plants are no way near dying but they dont look as healthy as previous crops. Iv fed exactly the same as in the past but this time the plants have developed gold speccles on a good percentage of the leaves. I was thinking of just feeding with water for maybe 2 or 3 feeds and watching how the plants react and also adding some nitrogen to the feed. Anyone have any other ideas or had this problem and can give me the solution that worked for them??? Any advice or opionions would be appreciated... Unless your completely new to this haha!!

With pictures you get better answers.

Agree with pictures. It very well could be a pest issue. The suck the life out of foliage, leaving spots.

Im not keen on the idea of posting pics on this site or any other. I dont think its a pest problem but i will have a good look for any signs of pests in around and under the foilage. I think it may be to do with a deficiency of some kind but it can b quite tricky to determine the problem sometimes. I think im just gunna play around with them abit untill i see the reaction from my plants im looking for. Maybe try adding some nitrogen, magnesium and pottasium. Not all at once but work my way through them until my plants react well.

Best I can do without seeing. Good luck

Gold Speckles or Rust Spots?? Rust Spots would mean CalMag issues in most cases.
