Early flower deficiency

[MostHigh]

I’ve had this problem since I started growing about 8 years ago. It always shows up in early flower. Most of the leaves get these brown or rust colored spots. Mainly around the edges. Anyone know what this is or what I should do?

Best guess would be cal mag . I have a similar issue when I flip. I had to start adding more of my Elemental calmag to my flower amendments. Hope you get your answer brother

I was thinking along those lines myself. I have a bottle I used to use some. Did adding the elemental calmag help the situation?

Interesting pattern. Do the necrotic areas align with the serrations from the other fingers?

The uniform lines, I see that too. That and the curled tips seems like it would be a calcium deficiency as leaves in direct light are affected more than those under another leaf. Soil or hydro? Could be ph ?

I had a couple plants a few years back that were "sweating" at the tip of the serrations and the light was burning the leaves under those leaves. Very similar looking but mine was dots about 1/16-1/8 inch.
