Q.Identify This Tree Please
I’ve been trying to identify this tree using all the tools I could lay my hand on. I am just not able to identify it definitively. My research tells me it is a bird cherry. I do not think this is correct due to the reddish hues in the leaves. The tree itself is relatively young, around 4-5 years. It seems to be a fast grower already 2.5-3m tall. Please help me identify this tree.

Those red spots that you see are a disease and possible nutrient deficiencies setting in.
I would test your soil and pH, as well as only provide extra water when the soil has a chance to dry out, very thoroughly, down to about 3 or 4 inches between watering. In reality, you should only provide extra water when there is a drought and the soil is completely dry down to that depth.
This is a page from UC Berkeley that will help you key out some of the more common Prunus:
