Day 38 since starting germination:
Everything is looking healthy and happy. I’ve FIMed the main and continued leaf tucking & LST. Upped the amount of Diamond nectar from 1ml/gal to 2ml/gal. Keeping the lights on 20/4 has kept the average low temp a degree higher at 66. I also changed the positioning of the lights. Now the Mars Hydro tsl2000 is providing ~500-550 ppfd across the canopy.
At this point the plants in the RDWC loop have different nutrient needs so when I did my water change I also changed the orientation of my buckets. I removed the bucket with the Northern Lights photo period from the loop so it could be connected to its own reservoir and be fed a veg nutrient solution while the Sour D auto gets its bloom nutrients.
