Calcium Deficiency?

heres a pic of 1 of my leaves. I think its a Calcium Deficiency. What do you think?

what type of water are you giving them? Are you using nutes yet? If so what strength?

i'm using filtered tap water with Botanicare Nutrients: Sweet, Liquid Karma, Pure Bend Pro Bloom my ppm is 1800 ph is 5.8

it looks like calcium deficiency from the blurry picture BUT yur 1800ppm makes me think it may be overfertilization.

too hot...drop the ppm
