What deficiency am I looking at here?

[barhoc11]

I have searched trying to find out what is going on with the leaves on my plants and think it might be a magnesium deficiency, even though I am using cal mag? Any help is much appreciated!

Just looks like a discolored leaf.

Lets see a full plant picture and one from above before we diagnose anything though.

Thanks for the response, here is another pic of the same leaf, a few hours later so you can see its getting worse...

Is that the only leaf that is having this issue?

There are other bottom leaves on this plant that are showing signs. The last picture is a different leaf on same plant

Do you have any epsom salt ? Use it to treat and prevent mag def.

Ive had something like this on a few leaves before myself. I just pulled them off and went on with the grow. Never came back and i never found out what it was. Doesnt look like the typical mag deficiency but im horrible with diagnosis so ‍

If it shows in new leaves at the top of the plant it's an Immobile nutrient. If it affects the bottom of the plant and older leaves then it's a mobile nutrient. How do the roots look? Keep in mind an EXCESS of cal can show up as a K, Mg, Fe, or Mn deficiency.

Any nuts u feed before? soil condition? temp?
Well the dropping and clawing could be associated with overwatering and cold temp,get temp up a bit close to 28 and that should help.
if its Mag def, U can do foliar feed with espsomsalt ,but not more than 3 times a week ( tablespoon per/gal with clean water ).
Lower the light intensity a bit until it recovering.
