Quick question would like some peoples input. currently have an afghan kush ryder day 36, in a 3 gallon container under a 400w hps. For the first 6 weeks my lighting schedule has been 18/6 under MH, i just switched it to HPS 12/12 due to having a photosensitive strain in the tent with the autos. I was wondering if going 12/12 on week 6 will lower the autos yeild even though they were under 18/6 for the good majority of there life. I was thinking running 12/12 for the flowering cycle shouldnt affect yield?
