1)The big lesson here is NEVER use chemical fertilizer, even just a tiny amount, on cannabis.
2) My other experimental lights are working and the whole plant is drenched in light, which it loves. (I'm happy to have flexibility with my lights.
3) I haven't watered the soil since the transplant. The soil is still moist and I expose it to a humidifier and spray the actual plant a few times per day, which it loves.
4) The plant is growing very quickly now and is already developing a side branch.
5) I'm keeping the water in the self watering reservoir at a minimum, just to have the bottom get some moisture, all good so far.
