nute burn or bugs?

[emerica]

hey guys
my plant is Elmer's glue
using calmag monster bloom and pure blend bloom every other watering after a flush or a tea
ph is 6.5 and ppms are 860
it's in week 5 was doing fine but then a few days ago I notice a few top leaves doing this
any help would be greatly appreciated thanks

those little dots looks like calmag overdose..

Looks like nutrient related issues, not bugs.
