Plants Herming out half way through flower

Genetics or bad light leaks. But imo, genetics if happening for a few grows once a certain week hits.

It is happening with multiple strains, multiple grows. Would the light leak only show is affect 6 weeks into flower?

I just don't see light leaks causing foxtailing

A simple door open for a few minutes a day is sufficient, so maybe you have been venting and not knowing it?

op said they do the same so its not the c02 ?

when I see yellow fingers its in late flower never early like op. I wonder if she's counting flowering times from day of sex or day of switch?

Im in my dark period right now, so I went to look for light leaks, didnt find any.

CO2 is at 1350
temp 82, humidity 42

Sunday April 30 was the start of week 7 of flower on a 9 week flower strain.

I'm not sure what you mean by - I wonder if she's counting flowering times from day of sex or day of switch?

I count flowering starting from day 1 of going from veg to flower, room and nutrients.

I said the same thing until i researched it. To be fair, I mentioned this because it's typically seen more from burners in the room. If you haven't had it happen to you yet, doesn't mean it won't.

ya those burners need to be cleaned at least couple times a yr,they sells tiny pics for that if ya getting any yellow flame needs to be cleaned

is your c02 running during lights out? or does your monitor have a photocell? and have you calibrated lately?

You should read about VPD. Your humidity could be affecting co2 uptake (possibly a separate issue).

if its running during lights out you're just wasting co2, they take in oxygen at night, only use co2 in the daytime.
not an expert by any means, but running it during the night cycle may not be a good thing, too much co2 means not enough O2, might be chokin em.

I went ahead and just turned the CO2 off for the rest of the cycle. However, I'm afraid the damage has already been done.

Some of the buds look like crap and smell weird. A lot of the tops are starting to foxtail.
