Hey Guys, I am new to growing and so far 6 of my plants are 3-5 weeks into vegetation now(Two Hydros, Two soil), I've noticed one of them (Growing with Hydroponic DWC system) has sort of a spotty discoloration. Not all leaves look like this, infact some look pretty damn good, its only a few that have this and it is starting to form on others in smaller spotty light blothces. If you can help me determine what that is exactly and how to fix it that would be great. Photo's are attached. Thanks.
Can you tell us what nutrients you are using in your DWC setup? What's your pH? What type of grow light? Can you give us a picture of the entire affected plants in the setup? This type of extra information helps us give you a better diagnosis.
