Today I added two 105 watt 2700k bulbs to the front of the closet, mid way half down, and not up over the plants.
I also replaced two gallons of water with two new gallons with BLOOM nutes in the water. I plan to do that daily now that I am on 12/12.
I did the change to 12/12 lights in one quick step, but I am graduating from VEG nutes to Flowering nutes and will make the transistion over 5 days.
Many growers do suggest a 24 hour, 36 hour to 48 hour total dark period when changing to 12/12. I do not do that. I have only read that some try it and claim it makes the change faster or claim they see flowers (sex) faster. I expect to see male flowers first and within ten days ffrom starting 12/12.
