Sugar Granny

VPD: VPD was 1.0 - 1.2 with 1.1 kPa avg Added heater to intake. 25-27 C Light: 475 PPFD / 20.52 DLI Watering: Watering with 6.5 pH aerated water 2 L in bottom feeding basin once every 2 days. I give it during night to avoid excess humidity during day cycle. Compost tea once every 4 waterings. Nutes/Treatment: Other: Using jute rope to LST to continue evening out canopy. Flipped to flower. Did a day on 15 hours then 12 hours. Took clones the same day I started the flip so I wanted it to be easy on her. crazy growth. looks the same age if not older than a week older plants. No haircut 4 plants in a 3x3 makes it very low VPD because of the amount of water in the top layer and/or bottom feed basin, as well as the transpiration from the plant itself. I only have a 4 inch inline so I wonder if a 6 inch will help this issue more.
