WHITE CRUSTshit on hydroton....

wht up, just noticing that theres this white crust shit on my hydroton pebbles around my plants... the plants look good but idk if this is mold or what?
plz help! THNKS guys!

No that's not mold. It's just the dried nutrient build up on your hydroton. Rinse with only pH water and it should clear up.

thanks mate

just excess salt buildup dont worry about it until you pull then sterilise all your equipment with diluted h202
