what does this look like

Heres a picture of a leaf, its out of a dwc system. what does it look like to you guys? It looks like moisture stress but its in hydro so i've never seem that before.

looks like a touch of cal deff. not a hydro guy so maybe wait for a hydro grower for input.

Yeah, does look like possible cal def. couple different causes..

where was the leaf from on the plant? Or better yet how about a pic of the plant?

also could use some more info on your setup if you are hoping for proper help.

its a new leaf, ie one that has grown since this particular clone rooted and was swapped into a res with nutes. This system has 5 plants in it 3 of the strain pictured above (sativa) and 2 (indica) not showing signs of stress. Ill try n get some more pics, AN nutes with humic and fulvic additions along with enzyme support

im gonna swap them to a fresh res and ill ph before It could be low ph around 5.5 locking something out in the sativas.
