Sorry ...you have a problem He is not a happy guy

Your frog will suffer from MBD ( metabolic bone disease) if the feeders are not dusted with a calcium/vit D supplement.
The symptoms are insidious ...the frog will be lethargic, eventually stop eating and jumping due to lack of the vitamin D and calcium. Sometimes one may even see the frog's jaw hang open and his legs looking really weak. If this has started ....it is curable..... supplements are an absolute necessity for a frog's survival in captivity. Plus, you have to consider how he was cared for ( ie vit D and Ca ) before you acquired him.

Water : if your water is chlorinated or treated a de-chlorinater is needed asap.

Get him off the meal worms --- they can cause an intestinal impaction ( blockage).
If you have not found any poop in the past few days, you should be suspicious of this.
Get him to soak in de-chlorinated water.

If the lighter green spots do not disappear over the next few days, I wold get him to a herp vet.
He may have parasites or an infection and will need an antibiotic and/or a topical medication to treat the spots.

Do you have a frog first aid kit ? If so, what do you have on hand ?

Has he been up during the day?

Is he spending a lot of time in the water?

I would make him a hospital/quarantine tank.....clean out his tank, replace the substrate w/ very dampened paper towels ( de-chlorinated water ) , his water dish and cleaned plants. Try to get things as high up as possible in the tank for him to climb on.
