@ShowyTreeivy19 Welcome to the Greg community! Honeysuckle leaf blight is caused by the fungus Insolibasidium deformans. The disease appears in the spring on newly emerging leaves. The first symptom is a yellowing of leaf tissue. This tissue becomes tan brown and finally necrotic and dry with brown areas involving an entire leaf or a large portion of it.

I'm going to disagree with @Ms.Persnickety . It does not look like blight to me.
Which is great news because blight is very, very bad. It's hard to treat causes necroses and the leaves would be very deformed sometimes curled and wavy.
What yours has is fungal leaf spot. Not great but not the worst either. It's a fungus so it does spread but can also be treated.
You will need a copper fungicide. Something like captain Jacks Copper fungicide will do the trick. The reason I know it's that is the leaves look fine, there is no damage to them. But the discoloration is indeed the fungus.
Now first I want to say treat the plant in the evening. This is important because if you do it during the day it WILL burn your plant!
It needs to be treated thought because the fungus does affect photosynthesis and the fungus will just spread and get worse.
Here is what to do.
1. Trim off ALL affected parts of your Honeysuckle. Don't worry if there isn't much left. I have a couple myself and they grow back fast. So don't panic if she is nearly naked! Throw those infected pieces right into the garbage can.
Douse what is left all parts stems, undersides of leaves, tops of leaves all of it! I would also spray around it as well. Those spore will have fallen all around it and you don't want other plants getting it.
3. Repeat weekly until you notice no new signs of it.
For future watering never spray the leaves it sits on them and causes fungus to grow. Water at the base only! This will help you avoid it in the future. ❤️
