My hydrangeas are planted on the east side of our house. I’ve had it two years and still no blooms. I bought one from a nursery and one from Ace hardware. Our soil is red clay. I’ve fertilized them. Keep them watered. No blooms. I thought Hudreanges were supposed to be easy. What am I doing wrong?
That is one of our most popular questions, I would say. You don't mention pruning, but that is often the problem. I'm also concerned about your red clay. Hydrangeas like well drained soil. Here are articles that should help:

My hydrangea has developed ugly black spots. What is it and how can I control it?
This is an ugly blight that shows itself in the heat, or when it is overly wet.
This is hard to control, but can be done.
Cut back all growth during dormancy down to about 1 or 2 feet. This should take out most of the infected portions making it easier to treat.
Next you will treat with a fungicide. This article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
I would also recommend treating the ground with DOLOMITIC LIME and WETTABLE SULFUR to ensure that what is left in the ground gets treated. It will be handy to keep these two things around, as they are good methods of solving infections in plants. They can be used once per year to prevent issues, or when ever you need for spot treatment.

my newly purchased 30/05/19 hydrangeas (3) RED BARON have not flowered and have now got brown spots that are getting larger can you help i have them singly in pots they have grown about double in size are well watered and fed i also added a 6 month slow feed at planting
It sounds like they may be a little TOO well watered. This sounds like, either, a fungal or bacterial infection.
In either case, a fungicide and removing the infected growth, as well as pruning the shrub at the appropriate time can help.

When should I prune my Hydranea Incrediball?
It is advised to prune during dormancy, which may be different in your country than here in the US. Between this time, and early Spring is the best time.
Since your hydrangea is H. arborescens, (just like the Annabelle) it will flower from new growth. This means that it can be pruned anytime as long as it is not blooming, or budding for blooms. Some people in prune them in Summer, directly after flowering, so the guidelines are simply for the absolute best time to prune.
This article will offer information on pruning different hydrangea types: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/prune-hydrangea-bushes-hydrangea-pruning-instructions.htm
Usually it's because the hydrangea blooms on old wood (previous season's buds) and they were pruned off.
Here are instructions:

I have 3 endless summer Hydrangea shrubs. They've always bloomed fairly well. This year,I have blooms deep in the shrub,I'm assuming from old wood,while it looks like blooms on new wood are now taller and blooming.is this normal? This first picture shows what I mean the best.
Yes, this can be completely normal. I would recommend cutting off those older blooms (those tucked away and fading) as they die off. This will leave the healhty ones to keep going, and even promote new flowers.
These are a type of mophead hydrangea, and are well suited for your area, and will sometimes need pruning anyway, if they get to out of control. This article will help you to know when to prune different types, but you will be concerned with bigleaf mopheads: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/prune-hydrangea-bushes-hydrangea-pruning-instructions.htm
