I have 15 plants(4 strains with 3 around 50/50 and 1 sativa dominent) that have all started flowering. I started them indoors. Took cuttings at 12-16 inches and put the plants outdoors where they got about 2 hrs of early morning light and filtered light the rest of the day. 2 qt pots that were kept well watered with superthrive and seaweed extract. After 4 days most started to stretch so I moved them to 4 hrs of morning light after transplanting into 1 gallon pots. Within 10 days(started outdoors mid April) all had started flowering. I've tried cutting a few back, used higher nitrogen nutes, making sure they get atleast 8-9 hrs of direct light and no luck. They're almost done and I don't want it to happen again. Any suggestions or thoughts would be greatly appreciated.
