re using water

I'm using foxfarms ocean forest 3 gal bag and a 2 gal bag of miracle grow perlite the water that comes out of the bottom is yellow and im not sure if o should use it but I Dnt want to waste any nutrients in the soil so I want to reuse the water is this a problem .any advice

This could be an ideal way to produce toxic salt build-up. It may cost you a few more dollars but putting your plants through possible nutrient burns and stressing them out, is it really worth it?

you bought the two most toxic soils in the history of herb should have gone with roots organic bro dont re use water or even use nutez for 2 months in that heavy soil

Throw it away, asap. The whole reason for watering til you get runoff, is to wash excess waste out of your medium. Never re-use it, ever.
