Sounds like moisture is getting in some how. I prefer doing ferts in 1L bottles of DI water, then measuring by the mL; the accuracy is far higher, and it's faster to measure doses.

I have chemicals which clump also especially gh booster. I use a mortar and pestle to crush it and mix it in a blender.

Use better air tight containers...........

Simple solution there.

You can also save those silica gel or add a small mesh bag filled with Rice and add those to the containers............

Rice will suck up the humidity.

They use rice in salt shakers to prevent caking.

But air tight containers work very well

My last two bags of gh booster were more 'clumpy' and sticky than I originally remembered and take more effort to dissolve, but N and P were fine.

I use the rubbermaid containers for each and they were great....

Just mix the dose with some water and dump in the tank.
