well being the smarty pants that i am, i was thinking it was saprophytic soil fungas, and i guess it could be salt too.
whatever it is, don't trip out and think it's cocaine and try to snort it!:blsmoke:
i've noticed useing fish emulsion outdoors really attracts the coons, they don't eat the plants, but dig them up. chicken wire is def. the best way to go till your plants get bigger.
i use mg organic choice, and it works pretty good. i read a post on another forum, where a guy had 6 plants in organic mg, and six in organic foxfarm, and they both worked the same. he did however have a problem with fungus nats in the mg.
