Last year my blue Hydragnea flowers were more pink and green than blue. I read to fertilize it and that should help but what fertilizer should I use?

blue(nico) hydrangeas can be made more blue by using aluminum sulphate as prescrkibed by the manufacturer to bring ten PH down to the 4.0 to 5.5 range. If you do not soil test begin as soon as yu start to get blossoms and add al/so4 every 2 weeks
I have three hydrangea plants that have done very well in the past few years. Several weeks ago, I cut off the dead flowers. Today, I went to check on them and am horrified to find that the end leaves are all brown and curled up. The leaves near the bottom of the plants are fine, but there are no buds and some large stems are almost all covered with dead and dying leaves. What is causing this and what can I do?
The plants may have gotten too dry. Hydrangeas need to be kept unifomly moist. Try increasing the water.

I am new to home ownership and plant care. I have several hydrangeas in my yard and did not realize they needed to be cut down at the end of the season. What do I do now? I started to cut one down and realized that the wooden branches appeared green on the inside. Am I supposed to leave them alone or cut them down? I'm very confused. There are new buds coming up from the ground, so I would think that the wood goes, but then again it appears healthy inside after I cut them. Please help. I don't want to ruin them. I love them.
Wait until it leafs out and then prune off what is dead. If you have not read it, this article will be helpful for the future: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/prune-hydrangea-bushes-hydrangea-pruning-instructions.htm

I have several hydrangea plants. Two are the same and are in pots outdoors. The one is doing fine. The other one's leaves were all curled and wet-like (gooey). Then I have three that are planted in the ground. Those too have the curled leaves and I don't think they look normal. Is there a bug that is eating at it (can't see anything) or some other disease?
It sounds like aphids or spider mites, both of which are quite small so you may need to look very closely to spot them. It could also be due to a fungus. I would recommend treating the plants with neem oil. This will treat both the pest issue as well as any fungal probelms. These articles will help:

I bought two Hydrangeas. I planted then outside and now they wilted. What happened and what can I do to save my plants?
Since they are newly planted, there may be gaps in the soil around the root ball that is drying out the roots. I would tamp down the soil around the plants. I would also recommend upping the watering. In addition, they could be suffering from shock.
