Auto White Widow

Till now, week 5, I have never water the plants. They had plenty of rain outside on the balcony. So now, in the beginning of week 5 I water them for the first time and for the first time add nutrients. They really look healthy and really took of. By the middle of week 5 they are already 30cm tall and side branches up to 10cm wide. Breeders say it will take 10 weeks from seed. So another 5 weeks. I also noticed that the roots in 8,5L pot have used all the space! You can see roots from the botom of the pot.
