Well, I don't know anything about PH and I bought the soil in a store, it came in a bag. I have a plate under the pot and I never let it dry out, but I don't put water directly on the soil anymore, nor do I spray the plant with water anymore.

I once had another plant and I sprayed it with water and it fell over with the impact of the spray and died. Very sad.

As to lighting, I have two lamps above the plant. When I am awake the plant has light, I turn the lights off when I go to sleep.

I don't want to "maximize the production values" or to "optimize plant flowering" - I just want to make sure the plant doesn't die.

Do you need any more info? Maybe more pictures?

Please, help me. I'm scared.
