Drop since flowering

Hi everyone I started flowering stage about a week ago but my plants are completely dropping since 3 days. Nothing unusual except temperature going below 15°C during night this week (25°C when the light is on). Is this drop normal in early flowering or could it be due to temperature?

Both of my plants are looking really bad at the moment, is this only cold to you?

I'd like to give you a picture but this website don't allow me drop url, as long as posting pictures. Can you please check on imgsafe this is the number 2e9e9dd459

15 C at night is a bit cold. Are these the same temps as before you started flower? You see what I'm saying; if the temps were this cold in veg, that's one thing. If for some reason it's colder now, that's something else entirely. If you went to 12/12 from 18/6, the plants are spending longer time without light so I guess that would mean they are exposed to more cold.

Can you stick a little heater in there? On nights where the wood stove wasn't quite keeping up I've had good results adding an electric space heater. The plants seemed happier in the morning.

If it is temperature related, and you add heat (shoot for roughly 25 degrees C or more at first) you'll know within 24 hours. When the plants are cold, all of their functions slow down. Transpiration, respiration, etc.

That's too cold! I've had plants hermie in those temps. I myself would stay above 19.
Good Luck

You can call it whatever you like. Am I sure? No. Can you prove it's genetics?
If there studies? I'm not being a dick, I'm asking because I want to know.

Well, considering that its perfectly normal for a plant to experience cold temps during its flower cycle in autumn, it just doesn't seem very likely to be a hermie trigger to me.

15C is 59 degrees. A bit on the cold side but not dangerously so. Plants have evolved around a day/night temp swing, so its perfectly natural - as long as its only a few hours at that temp, its not likely to cause any problems.

I live in Hawaii at an elevation of 3,000 feet above sea level and it gets below 45ºf at night and the only hermies i have had were from a genetic defect or when i purposely made feminized seeds with colidial silver

So is the conclusion that genetics (and GENETICS alone) can cause hermies? Nothing environmental?
Is this proven?

My situation that I described happened with two plants from different breeders grown from seed. If genetics is the only thing, why did those two plants both hermie? I know I have bad luck but shit, maybe it's getting worse, lol.

Were they seeds you bought from a legit seedbank? then if so it shouldn't be the genetics but if you just got it from a buddie or its some bag seeds its most likely genetics that causes it hermie

Do you take pictures with a bright flash in your grow room iv heard the flash shocks them and turns some strains hermie
No. They had no light leaks. The room I grow in has no natural light and I'm not much a picture taker.
I don't doubt that genetics can cause hermies, just not understanding if we know for sure if it's the only thing. Sounds like it's not.

Its generally going to be abnormal environmental conditions that stress the plant too much. Cool night temps are perfectly natural conditions for an autumn flowering plant and just are not likely to be a stressor responsible for hermies. In a sense, genetics is ALWAYS the cause for hermies, because the entire species is predisposed to it, its just a matter of how much stress it takes to cause it in a particular strain and pheno.
