Hey! so im running a drip hydro bucket system and im about a week and ahalf into flowering. So i checked on the plant today and I noticed that some of the clay balls have like a white gooey stuff on them.....like they had been sitting in water too long you know? Like......you know how the salts fromthe nutrients sometimes build up on a dripper system?....well it seems like they built up on the actual clay rocks....except imnervous it will get inthe way of my plants health. Is it just the salts from the nutes? should I just flush them a little bit to get the salts off? Or could it be some sort of fungus or mold? I hope not, i imagine it would be much more of a pain in the keister All help that comes my way is super appreciated! Check out the pics in this thread to see what im trying to say? http://forum.grasscity.com/advanced-growing-techniques/333962-mold-hydroton.html Thanks all and keep growing, most stuff i see on here is AWSOME smoke one!
