It very might be over fertilizing that is causing the roots to be burned. I would not use superbloom anymore. Consider (if you are not already) using a very fast draining soil mix. Perhaps if you were to amend your current soil with perlite to help drainage.

Its hard to say for sure but there also might be spider mites shredding that new growth. Good luck with it.

I was told to only water and fertilize as much as plumeria have leaves... So little or no leaves means little to no fertilizer and water. As mine have been leafing out, they are watered weekly and fertilized every other week so far...

Once a week with Superbloom is WAY too much. You need to repot these, the soil is probably almost toxic from the phosphate buildup.

I agree. Looks like the mix is so wet and compact. Listen to the others. Great Advice

Good luck!

You've only got two babies left!!! you must be so sad. Hell I'm sad for you! I'm a noob at Plumies and I'd say give those remaining new some new excellent draining dirt and then try to forget about them. and to keep your mind off those babies, spend all your hours on this forum looking at all the pretty pictures and soaking up all the good advice. =)

Definitely looks like over watering on dense soil which has led to poor root systems and possibly root rot.

If it were me, I would re-pot.. but only after gently removing as much soil as possible from the roots. You most likely have a salt buildup on going on down there from the 5 years of giving too many nutrient solutions.

The the root ball isn't very big or is limited to just around the base of the stalk, I might even take it a step further and gently rinse the roots to free them of any additional salt buildup.

Replant in a 30/70 perlite/soil mix and feed NOTHING but water and only when dry. If the soil is soaking wet.. don't water!

Keep her warm and as brightly lit as possible..

Thanks ever so much every one! I knew you'd have the answers!! Will I be ok to repot it even with us actually getting a hot couple of weeks in the uk ( yes honestly we're having a proper summer for once lol) I'll get this done tomorrow!

Donna, you can re-pot plumeria anytime. (I just re-potted one of mine yesterday in high 90's heat.) In the case of yours, I think the sooner the better! Good luck!
