You can find out if this is a "fast flowering version" by switching your light to  18/6 and if she starts pre-flower in 10-14 days or so, you have a fast flowering version. If that doesn't work, switch to 12/12. If 12/12 works, its a regular photo-period plant and an error was made somewhere. 

@im_sparky this is a good guess. Id switch to 12/12 at this rate just to see what happens... if it turns out to be a photo all along, youre prob root bound and need to transplant.

@chrisdoc80 They are screaming for Magnesium, and look to have also ran out of N. I would go easy on the N, but they need that for energy. Give them a foliar spray of 1/4 teaspoon Epsom salt per quart or liter when the lights are low and they will start to green up in less than 24 hours. I know you are thinking about flowering and N, but plants need N to build buds, especially if they are deficient, and the lower yellowing leaves are classic N deficiency.

I think your light cycle and genetics are probably the flowering issue. As mentioned above, I am betting these are fast flowering versions and not full autos. Use that to your advantage to stabilize them and get some healthy growth before cutting the light back to 18/6. your future harvest will be better if you do.

If he goes to 12/12, he wouldn't be able to determine if it was a regular photo period plant or not. But most fast flowering plants will start flowering at 18/6.  If the goal is to just get it to flower, then yes, get the plant healthy and then go to 12/12. If it were me, I would want to know if were actually a fast flowering plant or regular, but that's just me.

My first seed purchase was supposed to be a photoperiod but started blooming 4 weeks from planting on 20/4 lights.

My first guess is the same thing happened to you in reverse.

Looks very sativa ish, flip to 12 hours after you get her sorted and you'll be fine.

@im_sparky changed light cycle so see how that works

@chrisdoc80 interesting that they say quick flowering but mention 20/4 light cycles.  Not all fast-flowering strains will flip to flower on their own under that long of a light cycle. Interesting.

So are going to try 18/6 to see or just go to 12/12? Just wondering.

Good luck and keep us posted.

Hope I didn’t give you the impression I doubted that. I think there is another issue going on here as mentioned above. What schedule did you switch to?

By fast flowering do they mean the period from start to end of flower only? Some sativas have very long flowering periods, and getting it mature in 9 weeks is considered fast... about normal for an auto.
