Basil roots turning brown, seemingly healthy?
The roots on my Basil (grown from seeds) is turning brown, but seems to be healthy. It's very young, gets tons of sun each day, and it's been very warm recently (80+ f in my apartment each day), my other plants have been very thirsty, my cilantro is in the same soil and droops every three days, needing the same amount of water.
I water it when the soil seems dry to past my first knuckle (not sure how much deeper, i cant dig in that far), and when I water it, the soil seems to drink it up significantly. I can water a lot and it doesn't drain for a while, and this is well-draining soil. Maybe roughly once every week and a half at the moment? I just pinched the top of the tallest basil.
It seems healthy, but the leaves feel "soft". The brown is on three of the five stems here. They are separate seeds, by the way. Do I need to move or cut them now? Are they killing the biggest one?
