Curl leaves yellow-red

Hi @RENTON by your description and the appearance of the leaves it seems to me a lack of Zinc. the first symptoms are the yellowing of the older leaves, then wrinkled and curly of the young leaves, the plant becomes spotted. and in the last state of deficiency the tips of the leaves burn curling upwards and enter necrosis. good luck mate 👍

From what I’m seeing is your huis way to high and can cause a lot of stress! But in this time j oh f flower it is pretty normal to get some changing if the leaves due to the buds fighting to fill out as she comes to the end of her life! Try to get that humidity down one way or another and she should come around! Good luck 🍀👍

Is humidity below 40?
