Liquid fertilizer lost it's color?

I have a bottle of liquid potash that was pink but i accidentally left it on a table that was in direct sunlight.... it only got about 6 hours of direct sun but the liquid changed from pink to almost clear (very dull pink-brown).
Would this liquid still be usable?

I don't know if it would have just been some dye that lost it's color from the sun or if the whole thing was ruined.

Thanks for any opinions.

Should still be good. Keep stuff out of the Sun from now on.

Potash and other salts will crystallize with heat, water evaporation and/or direct sunlight. This might be the case. 6 hours isn't enough to ruin the stuff tho, give it a good shake before you use it next time. Should be just fine.. And yea, the pink is most likely dye.. Dark water absorbs more heat and light, so they tend to dye them shits with bright colors.

Like troutman and most likely the label on the potash bottle said, keep your nutes away from sunlight. Store in a dark and cool place.

Thanks guys

Yes, it was just a mistake, left it outside in the evening but didn't realize until lunchtime the next day.
