So far I have let my plants freeze, low temps, low humidity, overwatered, overfertilized, underfertilized, and have no clue what the PH is. I would say I have 4-5 plants that may not make it, they are still growing, but don't look healthy.
This one looks burned.
Even the twins are growing very slow.
The deformed plant is the best grower... short and bushy.

This is the most mature plant.
