It's been a long time since i played around, and I am having an isssue

I am having what I believe is a calcium dif issue. can anyone verify or let me know what I am dealing with?
I am in hydro, PH has been between 6 and 7. Nuts are per mfg. (Botanicare - CNS17 GROW)

Looks like it. Just need some cal/mag.

I think your ph might be too high. I believe ph should be around 5.8-6.0, big fluctuations in ph can cause problems.
Kinda looks like phosphorus def. to me, but I'm not sure.
I like this site to start researching issues I come across.

cal mag and phosphorus, probably from ph lockout or lack of proper feeding.

Thank you all for the information.
