<span class="link_user">@TroJanBud2</span>, it took 7 weeks of flower after I switch from 18/6 to 12/12. Looking back now, I should have wait at least 2 more weeks.. Very easy to grow, don't need much fertilizer. Good luck for your grow :)
Sadly I had to harvest 2 weeks early because they were both turning hermis :/ I'm still happy with what I got. 30 gr per plant but I overwatered them for a least a month and a heatwave made the temp rise by a lot (32°C for 4 days). I couldn't flush them either but still an okay taste and smell is pretty good/strong.
