I was about to say that. If it's first run you may not see it in clone. That's what my maple leaf indica is starting to throw now that she only has 5, 6 or 7 days left.it annoys me, but can't rule out mistakes (high Temps, if she is root bound), but it could just be genetic as the plant nears it's end of life.
If I ran any plant in a 10 gallon in my tent, I'm pretty sure it would over grow my space!
I do love goji. Only gal I got is what got me into Bodhi in the first place. Still running her, granted I cloned her during flower so I have to go through the ugly phase. Still need to get a pack, love how strong she I'd yet still functional. A good day smoke.
