Hey guys, Ive been growing for about 2 years. Me and my roomate have just started hydroponically and so far everythings going well ive done tons of research and am still doing so day and night. But my white widow has all of a sudden just started dying and yellowing up terribly, i took a pic to my local hydroshop and med shop and they said theyve never seen anything like it but i was almost sure it was a defficiency but its just getting worse.Also it honestly looks so much worse in person than in person, the colas are slouched now and just shitty in general. The only thing i dont get is why thats my only plant doing that i have 4 more in the same resevoir and they're doing great! Any suggestions would be appreciated. Thanks!
