out of 5 plants 2 still not really flowering, so I decided to cut them down as it is getting late in the grow and they are starting to weaken. So even if they start to develop flowers, the yield will be low so not worth the trouble. Gave away the leaves to friends that cook with them. So not gone to waste. Just waiting to harvest the last 3 plants. One is very tall, almost 3 meters, keeps falling over. Noticed lower leaves developing phosphorus deficiency, but read that it is not an issue for flowers as they suck down nutrients stored in leaves. Hope that is right. Flowers are getting fatter.
@Metatronix, Thank you, I will move them outside, hopefully the timing is right for Thailand as it should be December the dry season when they are flowering.
@Hydrostyle, thanks a lot, it was a lot of fun to grow them, I will do another batch of them after this next grow which should not take too long. Limited space in my garden
