See, this is a big misunderstanding of the word "auto". Auto means auto flowering. As it starts to flower on its own time no matter how many veg nutes you feed, amount of light it gets or any other way you think you can keep it from flowering as you would a photo. What "auto" deos not mean is faster flowering. Autos veg 3-5 weeks usually and than flower. This is subjective to whether its faster or not than a photo based on how each grow their plants. If i veg my photo 2 weeks and flip to flower than its not going to be longer than an auto. Autos still nees to flower for 8 to 10 weeks. 70 days is just not enough for 90% of autos.
