Please advise possible nitrogen burn

Some leaves are going almost gold! just put it in a bigger pot with a different medium
With worm castings in. And a few days later leaves started to go gold? Any one see this before?

Thanks!

No one has seen it before because you didn't post any photos

Your description isn't nearly as useful as you may think it is. Also you haven't said the age or size of the plant or many other details.... but i guess the same reason why you didn't know to mention them is the same reason why you are having troubles.

I suggest two things.
1, post photo's and forget written descriptions.
2, go buy a generic grow book or a cannabis cultivation text book. Read it cover to cover because trial and error will get you no where (unless you plan to live to 200+ years old, then maybe you'll finally figure out what's going on).

We need more info. It sounds like your new soil is too hot. Needed are picts, humidity and temperature of grow area, type of soil, amount of nutes, PH and PPM, if available. That will do for a start.

castings can be very hot, along with teas and manure, if you have a well balanced soil mix then you shouldn’t need them, remember less is more.

How did you come to the conclusion that gold colored leaves suggest nitrogen toxicity?
