I recently received several large containers of various ferts from a friend.

Some of them may have been left outside/god knows where for an unknown amount of time.

Most of them seem OK, but I have a 3 gallon container of Fox Farm 'grow big' that seems to have spent too much time in the sun. It has a good amount of brown chunks on the bottom of the bottle. It looks like the chunks came from a single thin layer of material that was allowed to settle and harden at the bottom of the jug. They resemble thin flat rocks that crumble under pressure. The chunks are not water soluble.

My question of course is can I still use this stuff? what problems could I run into? Is it possible that it is just one ingredient in the solution that ill be OK without?
