Post-mortem :( was a PH problem?

Why did you pull that up???? There's nothing wrong with that girl. At such a young age. PH rarely comes into play As they a absorb 90% of what they need from the air. (Hence the high RH needed) Also, you're growing in soil. Its very hard to get an off ph in soil. Especially not when it's a few days old. With growing this is part of it pal. If you're gonna pull up every plant that has an issue you're gonna be pulling more than harvesting. You'll learn by pushing the plant through. Also, the violet stem, is just that. There's nothing off or that would of stalled your grow. & she's droopy cause, the soil around your stem is wet. And what little roots are there were getting drowned.
