Sorbus sapling - Burnt looking leaves

[nikaia]

Hello

I need your advice please to help me with 1 Sorbus Embley sapling showing a few leaves looking burnt

As s per photos attached.

I raised this sapling from seeds

Of a previous 15 years old Sorbus

Suffering from fire blight.

I planted a now 3 years old  replacement sapling on our street Verge as a replacement of the old one.

Last year all the leaves were perfect

As my garden is sheltered but when I

Transplanted it on the windy street verge, some of the younger leaves started showing rust type colour.

In the last 2 weeks or so, more leaves turned rusty I have now sprayed them with a solution against fire blight..., composted a watered the sapling while waiting for some useful advice from the readers..

Many thanks in advance for your help, comments and advice
