Weird Autos (RQS NLA, same strain) still vegging day 50. Only some preflower, but nice plants. WHAT would YOU do?!

Keep the original light schedule.

Hard training and defoliation have extended the veg on my autos. On average they usually flower around 7 weeks. But this is after I cut back the light from 24 hours to 18 hours so I think this may be part of it. I wouldn't recommend increasing the lights after running them at 12 hours for an extended period of time. I had a grow where I increased the light hours mid flower and they started foxtailing.

From what I understand of Auto flowers. It auto flower's because it is crossed with a Ruderalis Cannabis plant and becomes an "Auto-Flower" plant. I would say this is not a guarantee of it going to full flower after maturity. The crossing of Cannabis is not a guarantee of both parent strains being present. Anomalies and oddities all over the place and depending on how far along the parentage is... Third.. Fourth.. whatever you don't know how much Ruderalis genes are actually there and therefore you could theoretically expect an Auto flower on occasion to not flower into maturity and therefore be Photo Dependant and not Auto Flowering.

@Bezzy Hi Bezzy changing the light hours for an autoflowering plant will have zero effect on flowering. If keeping the lights on longer isn't an issue for you then I would put them back on atleast an 18/6 cycle , The topping you did slowed them down a bit and kept them in veg for longer than normal but the benefit will be much bigger plants than normal. Dont do any more defoliation or topping and the plants should move into flowering very soon
