16oz dutch buckets orange sherbet

This little orange sherbet was topped on day 10 and is growing well. I ran out of calimagic due to a shipping issue. I was hoping that tap water would give them enough cal mag but the plants started showing rusty spots symptoms of calcium deficiency. The only cal mag that I could find locally is Gringo Rasta from fox farm. I gave her a dose of it but it is too early to tell if it is going to work. I am skeptical about any organics in my system from past experiences but the pH is holding steady after a couple days so hopefully it will work out. Other than that they are still getting 24 hour light and I am starting to think that I might have to figure out a way to spread the plants further apart. A couple of them are getting pretty big.
