Yes she is big enough for late veg just keep her there until she reaches the second fan.
Please don’t manually adjust water grobo sets water levels differently for each stage.
Yeah let her go, and like @Bplatinum9 said just leave the water, when you do your next drain and fill the water level will change because of the stage progression. If you extend early veg you’d keep the pod moist for too long and might onset damping off yourself by extending
Yep looks good👍
There’s a small spot of yellow on the end of the largest leaf. Should I be concerned?
Not unless it starts to multiply/spread
