I dont grow in soil, but it looks like overwatering to me. I've noticed my plants will only start consuming a half liter of water a day once they are about twice the size week 5 or 6 of veg.

scope under leaf for any tiny creepy-crawlies... Could be nute-related to. I'd get that pH up to ~6.8 or so in soil. That may fix the problem. Then re-assess. if it takes a major nosedive while maintaining regular fertilization and bringing pH up, obviously change course and disregard what i say. If they are reddish or rusty dots, it could be Mg deficiency... but you also need to rule out lockout from feeding too much of any p/k/ca/s. So, if yo know the ppms of what you provide you can make a more precise guess as to what course of action to take. get that pH proper first... solves a ton of problems on its own. Ensure no dry pockets when watering.. get it fully saturated and that takes a little runoff even if in soil. (soilless 20% runoff, full strenght nutes everytime -- i mention in case what i say has tunnel vision.. different ways of growing require slightly different practices at times)

My autos have flowered at various times. None earlier than 5 weeks I don't think without checking through my diaries? Id say they were all between the 6 - 8 week mark. I don't know enough to comment on the lights as the previous comment did as I'm not that versed myself. Hold steady there's still time my friend 👍 Good luck

No need to worry, cannabis is an amazingly smart plant and she is not dying. What is happening is vital growth elements such as carbs, sugars, amino acids, auxins etc which are "stored" in her older leaves, are being used by the plant to supplement flower growth. Cannabis does this because it is far more efficient to use the elements that are "stored" in her leaves, rather than making them from new during a high energy requiring activity such as flowering. Thankfully you have left all her leaves on, otherwise the plant would have to use energy to make those vital growth elements, plus using energy for flower growth. Had you taken her leaves off, some of her energy would be required for making amino acids, carbs, sugars etc as well as growing her flowers, meaning she would have less energy to grow flowers because some of her energy would be needed to make the sugars, carbs, amino acids etc. This is what the defoliation brigade fail to understand, not only are the leaves photosynthesising and making energy for the plant to grow, they are also "warehouses" for storing the vital growth elements for use during flowering. Therefore, what is happening is a normal process for cannabis during flowering. In future you could keep giving "grow" nutrients for the first weeks of flowering and this will ensure that your plants leaves don't go yellow as early. Congratulations too, your plant looks nice and chunky and I wish I could check it out in person! One other thing, try to pick up/remove any fallen older leaves from the pot and grow space, as leaving them lying around can invite fungal/mould growth. Hope this helps,.... Organoman.
