Week 12 of flower growth stopped.

You really need some photos to better clarify this issue. Or better yet, a Diary. growdiaries.com/diaries/248451-royal-queen-seeds-northern-light-automatic-grow-journal-by-wiffs-cbd/week/1382961 If this is the diary, and it was not linked I am along the lines of shit genetics. not all seeds are great just sucks you got one of the duds. The growth patterns looks kinda like dr.greenpoon, growen out for its weirdness not its harvest totals or anything elce. When you say "it grew the sack" do you mean "balls" like male parts?? if so, get it out of the tent asap or it will pollinate the other plants in their. I have only grown RQS once and I really enjoyed their plant. its high was not for me so never grew anything else about them, but some of their stuff does not seem up to par. And I think a lot of it is in their auto range.

???

Some will say bad genetics ( i hate RQS ) , but i met that grow pattern not once. Lack of light, too much nitrogen during grow and wrong balance of feed generally. I had such plants with outdoors grows, especially if i fed rarely or did not provide feeding at all, some girls went that way, despite sisters growing normall buds.
