Can organics burn plants?

I've been using down to earth fertilizers and about two weeks ago I noticed leaf burns and yellowing on leaves throughout the plant. A month ago I added half a cup of alfalfa meal, half a cup of neem seed, and half a cup of langbeneite. In May I added two cups of mykos bacteria and 2 tablespoons of great white to help process nutrients for the plants. Any advice about how to resolve the problem would be greatly appreciated. The plants were growing like gangbusters, but have slowed to 2 inches or less per week since the yellowing and leaf burn began 2 weeks ago. The plants were started indoors in March and were full rootbound in 5 gallon pots when placed outside in May. They have been in 32 gallon trash cans since May. There are holes on the bottom and sides.

yeah organics can definitely burn plants...I made the same mistake a couple grows back, liberal use of compost tea did the same thing to my plants ...btw nice name

Solutions? Can you flush out organics? Do I add more bacteria? Repot?
