On day 86 was watered with nutrients but it is possible within this week to switch to just plain water.
Side branches look mature enough with 70-80% orange pistils and started to turn inside but the main bud is like 50-50 white-orange and more of them pointing out. I think is due to heat stress as the main bud is closer to the light so the distance was increased around 15cm.
End of the week all side branches are now supported.
