The plant looks good.It's a mother plant I have for 4 months, I wanted to see if it I was root bound and eventually trim the roots, even If I was very weary of that too... I'm really a inexperienced grower... But upon seeing this stuff, I trimmed the roots and to my surprise it didn't stunt the plant that much.

My question really is, I guess, can it be another thing than fungus ? or am I simply wasting my time, because if I understood well, clones taken from a sick plant can have the disease, I have to start over...
