Late flowering question

[hillbillydeville]

Currently have 4 lsd 25 that are amazing plants. I'm currently at day 40. 2 of these started showing pre-flowers at day 20 and day 33. The last 2 still not showing signs of flowering yet, any cause for concern here?

I take it these are all autos but what is the breeder?

Good morning, fast buds

Can you post a picture of all of them? Most autos show preflower around the 20 to 30 day mark,so no preflower at day 40 is really late.

Are you growing under 24/0? I get some errant behavior growing under full on. I have one that got confused and I think reset its clock and is just now coming back out of veg at day 45.

That Ruderalis genetics is hard to understand. I think that there is more variation in the ruderalis parentage in use out there than is lead to believe. I am no breeder but that seems to be the wild card in different companies seed programs. Even after breeding them out to F4 and beyond there seems to be some weird things about autos. sorta cool.

Here's the family, the one that shows pre flowers started about day 20, there's one more that started about day 35. I use an nutes and 20/4 lighting under a de 1000 watt hid

Thanks for the pictures.There all looking great and at that size should all be in flower.The only thin you can do is wait a few more days and if nothing happens try and put them under a 12/12 light cycle.I realize this sucks and it's hard to say what the cause is and you may not be able to do this.

thanks for the reply, I was amazed at the growth of this strain when they get on the gas its truly a show.I have limited experience with autos and it just seemed funny that this deep in 2 didn't flower. I tried some different techniques on these and the 2 that are lagging behind one received only ponytailing for one week in 4 hr. intervals,the other received light lst both are late bloomers hopefully they come around Ive heard so much about this strain and wanted to try it.

HBD-- yeah, I think you got some "throw-backs", just damn bad luck, doubly so since you're new to auto's, and this is solid breeder- ... this happens on occasion, just like having a fem'ed seed turn male anyway,... the process isn't perfect, leaving you in an awkward position!
Your plants look fantastic, BTW! ...so, like Nammy here sez, best bet is to treat them like photo's now, a bitch we know! What nutes are you using, dosage, frequency? Along with the light reduction, maybe bump them with some bloom nutes too, just to drive the point home!
