Looks like you have some nutrient deficiencies. What are you feeding her, and what is the PH of the solution you are giving her?
Careful with that humidity level, it's rather low, and so you will need to make sure the soil doesn't stay dry for too long, while still avoiding over-watering.
@Eryan,
Thanks for the input.
I am aware of the need for bacteria, I am using compost teas on occasion.
I get my water from the tap filtered through a filter designed for hydroponics.
I then PH it around 6.5.
I will look into the deficiencies you referred.
Thank you !
@MagooYFZ, Using organic ingredients means then that you also need to have a somewhat living soil, with bacteria. So you can't use straight tap water for instance, because it would be chlorinated and kill bacteria. If it's been allowed to sit at room temperature for around 24 hours though it should be ok. To help increase bacterial activity in the soil you could add some worm castings or a worm castings tea.
As for what's deficient, it looks like they're missing Zinc. Possibly the start of phosphorus deficiency as well considering the reddish tints in some of the veins / stems.
The soil could be deficient, or the nutrients could be locked out due to PH not being at the levels it should be.
