Easy bud: a noob's diary

Yep thats normal. As far as I know, no you cannot affect when it flowers with a autoflower. You can expect it to get double as tall, possibly more. It depends on the strain, phenotype and other factors as well, but I personally go by about double the height.

No, it will not stunt growth. In fact, cannabis will produce more trichomes in an arid (dry) atmosphere than it will in a humid one. In over 35 years of growing, in my country, I am yet to meet anyone who uses any sort of humidifier when growing indoors. Most Indicas come from the Middle East, places like Pakistan, Morocco and Afghanistan, places with nearly zero humidity during flowering. Most Sativas from the tropics are grown during the "dry season" when there is very, very little ambient humidity. Your plants will be just fine. Hope this helps, Organoman.

In the end I'm not sure flushing did anything, I also didn't fix the pH, runoff is still below 6, but the symptoms stopped after several waterings with calmag, so I think it was simply a matter of water being too soft.

I would just give it water it still has stored energy it's pulling from leaves. Don't wanna add a nasty chemical taste by adding nutes now. You can probably cut in next few days to week. If you have a jeweler's loupe. I look at several spots and when I have about a 90 percent cloudy to 10 percent amber trichromes on the buds, not leaves. Is my personal favor time to harvest. More amber trichromes the more couch lock. Enjoy 🌱

Hey there Don Costro, so basically for drying you're trying to dry it for a long as possible. The more time a plant takes to dry the more i has basically been alive that whole time producing some very interesting molecules. Usually in your conditions, you should expect around one week. the best is two weeks, 10 days is common, some people even try to rehydrate it after the first week to make it go longer. Basically when you chop you should already know what is your drying environment. So if it's dry like yours up to 40RH so you should water the plant quite soon before the chop. Medium of up to 60RH then it less water before the chop and 60+ it should be quite dry. A lot of factors go into it. If you're brave one day you should look for the "bud washing technique" it's much superior for the cure and drying times and takes a lot of the variability away. Hope this helps ! 🚀
