Is this a Calcium or Manganese def?

I think this is the start of a Cal def but it also kinda looks like it may be Manganese. Its effecting some of the growth around the top of one of my plants. These are the worst leaves I could find to take a pic of.

Can you take pics in natural lighting please. The LED's make it difficult to see the colors properly. Thanks!

Edit: I can also get a good fingerprint match from the one photo... you may want to delete that one and post a new one with your fingerprints covered up.

Ya, shoot a pic under regular room light.
USUALLY, rust colored spots are signs of a Cal def. USUALLY.
What medium are they in? What kind of water you using? What kinda nutes?

when lights went out I looked at them and its cal.


Edit I could see the rust color come in a lot better. Still getting used to the LEDs. I ended up adding Nirvana thanks for the quick answers guys!

I am using my tap its right @ 55 PPM... Maybe not "right @" lets go with 55 ish, I'm using DAN's Connoisseur 2.35 flower and I'm trying A/Ns light feeding for base nutes. I think I'm going to get some Cal/Mg to keep on hand from now on. This is my first time using these nutes. Oh, they are being grown in hydroton.


The prints aren't mine. LOL

I'm not familiar with the nutes you're using.
I can tell you that you have perfect tap water!
I use RO water mixed with enough tap to give me around 70ppm. So, you could try moving your ph around (forgot to ask what your ph was) and/or try a little cal/mag.
I grow in coco and I shoot for 5.7-6.0 ph. (I used GH flora nutes, btw).
Sorry I couldnt give you a more direct remedy but knowing what the def is, is half the battle.
Cal def are easily fixed.

For years before I grew pot I knew the tap water here taste better then at most places. So when I got the TDS meter and tested my water I was really happy that I didnt need to install a RO system.. This is the first time I have used advance nutes too. I try to keep my ph around 5.6-6.0 but for 3 days its been slightly out of that range. 6.3 to 5.2 its possible that could be the reason also. Im home now so the PH issue is fixed and I added some Nirvana to be safe. If I remedy the Cal def will the spots just stay like they are now or will it just stay on the infected leaves and eventually take over the leaf?
