Well, for one thing, you've overloaded it with nitrogen... Fox Farm Ocean Forest is loaded with it (the NPK of the soil itself is 4-1-1), now you add dry amendments with 4-4-4 and you've got pretty hot soil. The yellow spots are looking like the start of a calcium deficiency - the calcium being blocked by the nitrogen overload.
If this were mine, I'd transplant into a larger pot WITHOUT the amendments (it needs it anyway) and give it only pH'd water for a couple of weeks. The soil will feed the plant for those weeks and hopefully doing this will allow the plant to take up the calcium it needs.
Good luck...
