Yellow stuff on Annual plant

I could really do with some help! I'm very new to gardening and have a new little flower bed with a number of different plants. It appears there is something wrong with my Daisey Bella as pictures show there are patches of yellow all over the leafs and now up the stems. I have a number of them in the bed, but only this one looks like it has a problem. I have taken pictures of a newly planted Dahlia that is in front and the leaves are starting to look funny also - from the other pictures you will see there are a lot of different types of plants in this patch and they all look fairly ok - I have a small dog and every now and then I see him pee on a few plants but it is not like a usual pee plant. I have a two prong PH tester and tried to see if it was something to do with the soil. The reading are all over the place depending on where I put it - readings show anything from 6.2 - 7.5 - I have a fairly heavy clay soil here - does anyone have any ideas what is wrong?

Tricky to see properly, the stuff on your daisies looks like rust, but can't see properly.
The interveinal chlorosis (!) on your dahlia can be caused by a number of things.
It could be magnesium locked out for some reason.
You can try a dose of epsom salts - a teaspoon in about 1 gallon of water, but don't over do it, or you could then lock out another nutrient (calcium)
It can also be just that your dahlia is growing quickly now and it's not getting nutrients into its system as quickly as it would like, in which case it'll be ok in a week or 2.
See what other here have to say
and good luck!

Thank you Pete8
I will take your advice on the Dahlia and leave for a week or so and see if it is just where it is new in the ground 
This planting stuff is heart wrenching - they are like me new little babies and hard to watch when it looks like I am killing them 
Thank you for your thoughts !
More often than not we kill plants with kindness.
If it's the right plant for the conditions you have then the plant will be fine.
It could also be your dog pee stressing the little plants and leaving them vulnerable - you should see the state of my lawn!
