I have a blueberry kush at week 5 of flower. I started noticing these reddish brown dots near the center vein and the fan leaves. Now it's just becoming more and more. Leaves are beginning to lose its green color and now is pale greenish with lower leaves yellowing. Assuming I have been under feeding . Could the dots be because of ca mag def? Or possibly phosphorus ? I'm currently using GH bio bloom and bio bud with ca/mag and botanicare sweet raw. Apologize for the lines I didn't wanna have to kick my hps off.
