lilac problem

My lilac has developed yellowing between the veins. The green leaves are kind of crinkled. I've treated it with liquid iron but don't know if that's the problem. I can't find any lilac problems that describe these leaf appearances. Can anybody identify it for me.

I'm betting by now you're already seeing the benefits of the liquid iron as this does sound like malnutrition (a good feed with blood meal or some other slow release organic fertilizer wouldn't hurt, either).

If these things aren't helping, it could be viral (the symptoms are similar), and that would be a different story. It's either destroy affected tissue or hold 80 degrees for three or four days to destroy the virus; pretty hard to pull off. Hope it's greening up for you...
