when I first started growing I didn't understand that the time seed companies list is mostly weeks flowering I thought it was from germination to finish so I started 8 different strains of photos thinking my autos would be finished before my photos were ready to put into bloom. I kept the photos under regular 42 watt flouresceent bulbs while in veg. and moved them to my tent to start adding height. now they have really taken off and are about 8 weeks old now and are ready to flower. my question is can I change my tent over to 12/12 to start my photos in flower while also finishing up flowering my autos they have about two weeks left and have already developed pistols are turning brown just have not showed any Amber trichs yet. or will finishing up on 12 /12 greatly lessen their yield?I am just afraid that if I keep the photos in for another two weeks they are going to be too big by the time the flower growth spurt hits. I guess I could top them but if I top them won't that set them back a couple more weeks and then I will lose the growth I wanted. any words of advice would be greatly appreciated.
