That kind of looks like a hermaphrodite plant to me... I'm not 100% but those look like nanners or pollen sacks all over. Wait until someone else confirms this though, I am not an expert. The reeeaaally strange thing though is that they are purple/ almost brown looking pollen sacks.
Either this is an incredibly uniquely colored strain, or you got something fucked up here. I've never seen any sort of nute burn like that. The purple stems can be a potassium or calmag deficiency, but often times that is just the strain.
Wish I could be of more help.
