Three plants in a small tent. Only one has this issue. All are about 3 weeks in to flower.

Checked the undersides for spider mites? Thought I had a cal def, turned out to be juice sucking arachnids. Neem/aza wiped them out but the damage is done. Try getting the white balance on your pics tweaked so we get a better idea of color..

And a big hello from MN.

nute companies take in to account that most people use tap water and tap water has calcium in it, so when using RO water if your not using a nute that is made for RO water you will get the calcium problem
