Cal mag deficiency?

[Cheffrey]

Is this calmag def? Anything else?

Thanks

it depends on where the leaf came from. it is impossible to completely diagnose this problem without seeing where on the plant it is, because it is EITHER a calcium or a magnesium deficiency, but not both.

Doesn't look like a magnesium deficiency, to me. I'd expect the "veins" to be green while the areas between them yellowed.

But, as Emilya stated, you haven't presented enough data to determine exactly what the issue is, and certainly not enough to even guess at its root cause. Please provide more pictures - old growth, new growth, and entire plant. Also mention what, how much, and how often you are feeding it. Also the water source. Along with pH information. And what type of media the plant is being grown in.

There should be a stickied thread near the top of the list that explains what sort of information a person should provide when asking for Rx assistance.

EDIT: I did not realize that you'd posted this thread in the general Frequently Asked Questions section instead of the Problems, Pests, and Disease Control one. Here is the thread that I was referring to:

calcium deficiency then, because being at the top it is an immobile deficiency and that points to calcium... now we poke around for the cause. Are you giving her any calmag at the moment? Do you adjust your pH? Are you using filtered water?

 

[Cheffrey]

Filtered water but minerals remain. I started giving a calmag supplement a week and a half ago. I ph it to 6.8

Hi Chef

3 things well if you include yes and a nod to the above information already given to you, those things also.

1. Calcium def and maybe starting to get a little hungry overall.
2. How old is she?
3. Reason? Have you checked pH? It doesn't absorb in a large pH range, minimal when you compare it to all other nutrients cannabis needs.

I have found that a slight pH adjustment paired with a shot of a pH balanced Cmag supplement will help stop the spread. You will not be able to save the leaves though, they will remain spotted. No biggie.

 

[Emilya Green]

Ph adjust to 6.3 in soil... 6.8 has you out of the usable range as soon as there is even the slightest upward drift. This could be part of the problem. If you started at the lowest dosage for the calmag, try the max dosage now that you still have the problem.

Ok awesome, thanks for the help!
