Well in either of the cases, weither I decide to test the soil or use
various types of getting more nutrients in how long should it take to

Presumably the best time to treat the deciduous is in the Spring?

IME, correcting chlorosis by treating the soil with whatever can take
several weeks to show an effect. AS DT said, one's first reaction to
chlorosis on a chalky soil is iron and/or manganese deficiency,
although some of the plants you mention (e.g. lilac) should be OK, but
the rowan might not like it. I'd water them with some ericaceous
fertiliser (Phostrogen and MiracleGrow both do one), and that's
certainly simpler/cheaper than getting your soil tested. But whether
you'll see any effect before they shed their leaves in autumn is
questionable. As you imply, next spring perhaps.

As an afterthought, they're not just dry are they?
