You should water the soil completely, with at least some runoff (10% is typical advice). Sometimes people water around the stalk, and get dry spots in the soil. That can cause deterioration. You want to completely drench, then let it become almost too dry.bottled water as needed(about every 3 days or so when soil dries out).
I'm not sure what nutrients were given (of any)before I started trying to save this plant but I haven't given any.
Is that plant closest to the light? Or, to a fan?There are 3 other plants in the tent that are growing fine. But this one has had leaves curling up and dead tip since before I took over their care. The plant is still growing but slowly and with curled up leaves.
