Bibi2024started grow question 2y ago
Leaves are curling up and the flowers are taking on a light purple color - is it due to temperature?
Outdoor/unknown strain/more sativa since it started flowering very late.
In bad weather, it is covered with flies and protected from the rain with transparent film (on top and the weather side).

Purple colour is almost certainly due to cool night temps.
Curling leaves are most probably a sign of a magnesium deficiency...........it is not related to "light stress"!

There are 3 reasons for purple flowers, but usually, it's due to temperatures and genetics, and that's fine. The curling of the leaves upwards at the tips of the plant is a reaction to light stress. Since you can't hang the sun any lower...
P.S. Really beautiful plant!

That's definitely due to the cold at night.
Cool, damp weather and fluctuating temperature/RH can promote fungal diseases like Botrytis/bud rot, so be careful. Small yellow/brown & curled or "mushy" sugar leaves coming from the buds can be an indicator.
Wishing you lots of success and good weather!
