Is tiger bloom now green in color?

I was measuring out some tiger bloom just now and when i opened a new bottle the shit was a different color. Not padres brown like the first bottle but just slightly greener then the grow big. Just making sure they didnt screw up at the plant. I shook it up too..

I noticed this last summer. My first bottle was definetly darker than when I went to get more later in the summer. It still works good!
