When to turn to flowering.

Good afternoon, U Since it's a feminized strain, you can keep it in the vegetative stage (almost) as long as you want or until it reaches the desired size. However, you should keep in mind that the vegetative stage is crucial for a good harvest... Maybe you should review some key points to maximize the plant's potential. I would let the plant grow a bit more, but it always depends on the tent you have...

In my opinion, you can send them on time, but I would take care of their nutrient situation first to make sure they're doing better... I can't tell you exactly what it is because there are no parameters, etc., but either they are too dry/too wet, which means blockage, or they are lacking NPK, especially if you want to initiate flowering. Just because they're lacking doesn't always mean that adding more will help... Check the pH value beforehand if possible (medium/drain/watering) and only increase fertilization once you're fully in the range... They look quite pale around the 👃 But it'll be fine 👍

Still to early' though you can shift da light schedule by 1 or 2 hours more light :) Da best indicator is when little leaf starts sprouting at da stem.

1st thing you need to do is transplant that plant into a bigger pot preferably a fabric one, with the base of the plant level with the top of the pot, water it thoroughly wait for dry back before next watering and wait a few weeks for before flipping to flower. You should be able to manipulate the plant while waiting to flip to suit the size of the tent.

@Altitonans_Fulmen I though exactly the same with anerobic iI bet that soil whiffs a bit..

When about half the area is filled... if other issues limit your ability to do it right, do what you gotta do. - Other options include super cropping or whatever dumb label is made for simply breaking stems down to a lower level and allowing them to heal -- viable as longn as branches aren't so brittle they snap off completely.. comes with some risk. Using a scrog in future can help save a lot of vertical space too. level it out at a point where it will have room to grow vertically at a time of your choosing.

The humidity from the top of the soil to the top of the pot must be incredibly high in there; fill the pot to nearly the top. The high humidity is destroying any real growth. The plant has been grown with a massive shortage of oxygen. The pocket barrier of high humidity above the soil will prevent efficient oxygenation of the soil; in a plastic/ceramic pot, it's practically a death sentence for meaningful growth indoors. If it took 12 weeks to get to that mass, there is not much point in flipping until your plant is actually converting a reasonable amount each cycle. Possibly the first plant I've ever seen grown entirely using anaerobic fermentation and still be alive & kicking; that's what happens when you go from 38 ATP per glucose molecule and drop down to 2 ATP When you leave a deep, empty lip at the top of a pot, you create a stagnant "microclimate" trap. Growing for 7 years, dude. Need to get back to basics. Best of luck.
