I’m noticing minor spots and burnt edges on the leaves. Should I worry?

Looks like something is off. Email grobo at support@grobo.io and send the pics. Theyll likely check your water etc

Do a probe health check! It probably needs a cleaning and to be recalibrated 
But also send a ticket like Todd suggested
