No, it looks all good. You need to keep it covered with a breathable material of course and not move it for about 7 days. This will allow the pellicle forming on the top to completely grow and seal out competing bacteria and yeast. I think of it as an umbrella while the real action of converting your sweetened tea into kombucha happens unseen underneath.
Temperature is important too, don't let it get too cold or too hot, between 75 and 80 seems to work well.
Good luck!
