Day 38 since starting germination:
Everything is looking healthy and happy. I’ve continued leaf tucking & LST. Upped the amount of Diamond nectar from 1ml/gal to 4ml/gal and added Liquid Koolbloom to the feed. 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 Atreum hydra-3200 is providing ~700 ppfd across the canopy.
At this point I’m starting to feed for flower so when I did my water change I also changed the orientation of my RDWC 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.
I’ve seen some saying a ph of ~6.5 is more ideal for autoflowers so I will be trying that this feed…which works out nice because my solution happened to be right there after mixing the nutrients.
