Late to start budding

Hey mate ;i had an auto northern lights that matured at 6 months..!!! Yes 6 months... though one of its main branch was fully mature and ripe while the rest of the plant was still vegging!! What caused it was i used red blue leds for 40 days of its growth and then started using cree cxb which was 3 times the wattage than before red blue! So when you change lights for autoflowers;it can at rare times trick an auto to reveg or a part of it to reveg ;this is one of the techniques some growers use as i got on google. A unique experience indeed and she would yield a lot more than other autos.
