I think you may be right. I had just watered them. I was using a bottle with holes in the lid but it was taking too long so I just opened the bottle and poured. Lesson learned.
Try various types of pots and see which you prefer/ have better results with. I'm currently using plastic pots, someone on here did tell me the roots may get too hot in the plastic pots but so far they seem good.
Yes you're probably right. I'm just thinking what would happen in my country. Hope it works out for you. I have two Autos in my ensuite bathroom, they are not even budding yet and they stink the room. I have no filter or anything. Good luck with your grow.
Regarding lst
I just tied one of my plants yesterday but today she looks very droopy and unhealthy overall
Could this be the reason ?
I don't think lst could cause this but I couldn't be 100% sure. Mine looked very healthy the next day.
