Sorry to know about the problem with the ph-nutrients @juh Anyhow, the flowers are still developing very well i think she will be ready for harvest in approx 2 weeks (unless she suddenly wants to reflower after correcting the nutrient intake).
It can produce some bananas indoors in late flowering, especially if you push her too much with ferts and flowering stimulators.
Anyway, hope it didn't harm @juh and congrats on your harvest, a great looking purple haze tamed expression, glad you managed to amend quite well the problems in mid flowering, not easy to do it once flowering is advanced
