I think I am. As long as I can smoke it - why shouldn't I? It's my first time of growing, so I don't want to waste anything.
And yes, it had some stress. I two clones from it. And I have another (same kind) plant - it had one clone cut off it. It's showing the same symptoms. It might be of pH inconsistency. It was mostly 6.3 and recently I got it once to 5.5 by an accident and all of the leaves started make yellow spots. So I flushed the plant with clean water and waited for it to dry out. Now the spots are almoust gone.
