Leaves are getting dark
Leaves are getting a little dark and cotyledon seems a little sad. I suspect it is caused by not watering her enough (i was only spraying her with water the first 4days) Any advice?😀

Black spots?
Is this a deficiency, nutrient burn, or disease, growing in MG soil, recovering from overwatering as well.

Weird coloured leaves
The leaves are yellow a bit on the outside and just today noticed that it looks kind of black too. Anyone know if this is because of a certain deficiency?
