Q.About NPK
I have been given a liquid fertilizer called Algoflash all purpose and it has a NPK of 666 on the bottle. They say use it on all plants every time you water. Is this right? I grow veggies and herbs, but this sounds fishy to me.

Yes, as far as I know this fertilizer is good for just about any plant, including edibles, and safe to use. As with any fertilizer product, be sure to follow label instructions carefully to obtain the greatest results.
