First, I even don't think the "balls" is a bad thing, if you let the balls open, you'll get a lot FEMinized seeds, so if you want, just keep them.
the pic shows the under leaves getting yellow form the tip to the center, It is a nitrogen def problem, give some nitrogen gonna be fine.
Eleven pix they've been taken at: Aug3-Aug5-Sep1-Sep8-Sep12-Oct17-Oct25-harvested and moved indoor at Nov2-Nov7-Nov11-Nov13.
It was a random seed, germinated in the July, and put outside, fert with the nature fresh horse shit and bat shit, after harvest, I moved her in...
