Keep the fans less nutes homie. I feed every other time and they love it. Make sure it has an open root system when inducing onset, so since you switched to 12/12 the plant wants to shoot so its roots 2. transplant into somithing about 2 gallons bigger. Do not feed your plants every watering they need to be flushed so the nutrients dont build up in the soil. Easy way to keep that from happening is to foilar feed or spray them. Be sure to not spray under lights as your plant will burn. You will be fine just transplant and give it a couple of plain waterings. I have a plant thats doing this only because she is in to small of a pot.
