I'm trying to figure this out. I've never seen mottling like this. It's happening to 1 of my 2 blue dreams. Outdoor soil grow. Ph was 6.4 this morning. Have been treating with some cal mag on top of foxfarms schedule but am holding back because they got the claw a little bit. Plants are in 3rd week of flower. Overall garden is healthy. What could this be? It's on most of the plant...
Looks like calmag def to me, water with some epsom salt 1tsp per gallon, and 6.4 ph seems low for soil you want it closer to 6.8 to 7
