Looking a bit small!

At this point, there's nothing you can do, since it's in full flowering mode and it will barely grow anymore. You kept it in a small pot too long. Nothing wrong with starting in a small pot, but autos need to be transplanted to their final container rather quick, during the 2nd week of veg, usually around day 10 of veg. Or you can start them in their final pot.

Hey mate, she went into flower pretty early so you just need to see how much stretch she will have left, she has a few weeks in front of her still so there is time to put on a bit of size. 💪 I would slowly remove the grow and increase the bloom next week to 2ml/l. Other than that your parameters look good ( ph, temps, etc), good luck with the rest of your grow 🙌

@BlueberryDagga They still have about 6 weeks to go So plenty of time to fatten up in the meantime Just watch you don't overfeed The burnt leaf tips are a sign of a past overfeed. Keep up plenty of fresh air flow to the plant and in aprox 6 weeks they'll be ready or almost ready to harvest 👍
