So I’ve been growing autos for several years and I’ve never had this happen until this 420 fastbuds Original Skunk auto decides she’s gonna give it go . Now this would be my 3rd run this year with autos and just like every other grow i clean every piece of greenery off the plant when harvesting and then I just sit the pot and stalk off to the side except this time when I went to dispose of soil and stalk it had new growth on the lowest branch so I stuck it back in the tent and roughly 45 days later I harvested around 24-26 grms of some even stronger smoke and I did this 3 more times and it’s still going as we speak first main harvest was 73 days from sprout so there’s a significant decrease in flower time . One thing I did notice is all new foliage is only 3 finger leaves every time it reveg’s it’s always 3 leaves. Any input would be great pics are not in order but you can tell each new veg cycle
3 point or 3 fingered leaves can be a genetic thing. However in your case I would have to believe it is a stress induce reaction. There is a term I belive heterophylly? You might look at that for your answers.
