It’s been getting cold. Today the space was a little warmer but seeing temperatures range from 57-70 in the space. I may stick a little heater in there at night. I have been letting them get dry since I accidentally overwater. Keeping nutes to 400-450 if needed and ph 6.2-6.5. Added a little kelp with the last watering. Watering 1/2 liter every 4-5 days. This one is drinking more. I have been petting the apical tips open to tighten node spacing now that I have 8 mains. I read somewhere that doing so triggers the next apical tip to emerge.
