m0useanswered grow question 3 years ago is the question what are they?
or is the question are they broken?
The green circles are not fully explanatory.
I cant find a LED map of what ones are IR/RED for that light. But if you turn it off it might have a small label next to the diode, if its different then the other brighter red ones I think what was said below to be true, its the IR diode. The lights I use have different labels and connectors on the board for different diodes so I got lucky.
Granted if its the same, then maybe reach out to mars hydro directly to see what they say, maybe it is fine maybe not.
Best of luck!
