This was kind of a crazy week in terms of the grow. I am posting this on day 9, when all the pictures above were taken. All three seedlings loved the weak nutrient solution I put them in. Seedling A is definitely going to be the chosen one, but I haven't yet culled C. I noticed the Rapid Rooters starting to break down, so I'm going to need to keep a better eye on pH. The water I removed from the reservoir had jumped from 5.8 to 7.0 pH, so I definitely want to control anything like that. I also added a Vicks WarmSteam vaporizer to the room my tent is in to try to boost the RH. Currently, my RH is rising by roughly 1% every few hours. Seedling B's nutrient tube was knocked out on Thursday, and it was pulled to save time. Thursday, I drained half of the existing reservoir and topped it back off with solution at 1/4 nutrient strength to boost the levels and step up to today's reservoir change to full 1/4 strength solution. I am going to keep checking every day for light/nutrient burn. I have debated bringing the light a bit closer, but I don't think I will for now. I plan to try to add mid-week pictured, but we will see.
