I have tried looking up for myself what this could possibly be but there are such similar discolorations i didn’t want to be wrong and try a wrong remedy this far into the growth process. I’m just confused because this one and the plant in front of it are being cared for the same way and the discoloration is only happening with the one pictured. Any help would be greatly appreciated!
Some info on your grow is helpful. It looks like a nitrogen def. But without your ph and ppm numbers it can be a guessing game.
