I had 6 PJMs planted 2 years ago. Last 1.5 years two of them have weird leaf discoloration. The other 4 don't. I'm. It sure what this is. Can anyone help? I'm posting a picture of the leaves. Seems like the leaves are dark green with yellow patterns/spots.

Hi Ilya, I don't know what PJM stands for but just thought I'd say Welcome! to the site! I'm sure someone will be along with help soon if they recognize the plant.

Welcome!

It looks very much like this picture, which is said to be lacebug damage. Have you checked the plant for pests?

I don't know what PJM is either, but that looks like mite damage to me.

My first thought was mite damage too but I didn't know what the plant was so didn't want to offer advice.

This Mobot page explains what PJMs are - they'll be more familiar to those of us in northern climates:

Thanks all for the replies. I'm pretty new to gardening so any and everything helps. PJMs are Rhododendrons as Sie was so kind to link to.

Yep ... I'm waaaay south and although I know of Rhododendron, I'd never heard of a PJM group. Green Grin!

We can always learn something new on this site. PJMs are not something I'll ever be growing, but knowledge never hurts. Hilarious!

I have a PJM -- my thought was that the yellowing was caused by chlorosis due to soil with too high of pH. Ilya, do you use an acid-lover type of fertilizer, or anything else to lower the pH of your soil?

Again, thank you all. I applied Bonide Rose RX 3-in-1 spray, which should take care of mites.

@Weedwacker, thanks for the tip. I checked the ph level of the soil and it seems around 6.5. Generally, I think we're until it hits 7, right?

Thanks again all. This forum is great!!!

Did you look for the lacebugs as mentioned above? Here again are the pics of their damage and the bugs;
