hey, im currently growing 3 ultra lemon hazes which are currently on day 56. I would not recommend auto seeds due to their inconsistent and unstable genetics. had my 400w hps on 18/6 for almost 7 weeks with no flowering. Threw it in with my buddies photo and am seeing strong bud growth already. Auto seeds uses the term "super auto" to describe this strain but the ONLY super-autos out their are stitch's genetics. the real super autos from short-stuff and flash have zero ruderalis in their genetics, which greatly increases yield. Dont get me wrong, they are in 2 gallon pots with FFOF and are approaching 3.5 feet tall with an insane amount of bud spots. And even though the plant has no resemblance to any haze( or sativa) whatsoever, It is definately going to be a high yielder. i did not intend on purchasing a photo strain. In order for a strain to be "auto" it must flower under 24 hrs of light. I was willing to stoop to 18/6 to get those girls to flower but to no avail. So all in all, when I asked stitch about these so called "super autos" he replied, "I personaly don't give any credit to this new seeds bank that use popular names just for selling, without any stable auto strains and also using the term "Super Autos" when those THINGs.... ARE NOT Super Autos..."
If you see a clear problem with changing your light schedule to 12/12, I would recommend going to 16/8 or 14/10.
