Hi,
I have a recurring problem for the last 4 grows, when I turn on the co2 the buds stop growing/swelling and start premature ripening.
The grow tent is in a lung room and I'm only adding co2 during the day, at night the lung room is open and there is fresh air coming in the room. Co2 comes from a bottle and is controlled by fuzzy logic controller.
At first I thought it was nutrient or led light related but I tried different nutrient lines and media, coco, rockwool and soil (soil grow seems a little less effected by it but still not how it should be)
Tried slowly increasing the co2 day by day, starting day one flower at 1000ppm, starting in week 4 flower after stretch finished it doesn't seem to matter.
Every time after I start the co2 it's a matter of 1 week and the buds stop swelling en will start ripening and I will end with very small buds and very low yield.
It took me some grow's to realize it has to be related to the co2 because all other tings i already changed basically.
I hope someone can help because this is extremely frustrating
Here are a couple picture's, you can already see the weird bud structure starting to form in the first pic around a week after I added co2.
week 4

For comparison the same clones the same day without co2
