I beleive this maybe the start of a cal/mag def

[WarBux79]

The title is a bit off. I dont mean Mag I mean Manganese def. I think this is the start of a Cal def but it also sounds like it may be Manganese. Its effecting some of the growth around the top of one of my plants. Could anyone verify this is the case? These are the worst leaves on the plant. I want to fix the problem before it gets any worse.

When the lights went off It was a lot easier to see the spots. I added Nirvana @ full strength its the only source of Calcium I have. I think I should order some cal/mag.

That's all well and good, but if it's a Manganese def you'll need epsom salts.

When the lights went off it became a lot more obvious it was surly a Cal def and not Manganese

Did you order that cal/mag? How are they looking? Any better?

Hey DD, I did order some Sensi Cal. The def doesn't seem to be spreading. I think it was caused more by the PH then anything. I will be posting new pics tomorrow in my grow journal.

I am a TOTAL IDIOT!!!!!!

Epsom Salt is Magnesium Sulfate, not the Manganese Sulfate I was thinking of.

Sorry for the senior moment.

Yea looks mike magnesium defficiency,,

Magnesium an dNitrogen defficiencies are hard to tell apart but heres a lil pointer..
on onlder leaves(fans) or from the bottom up
Mg deff. starts at the tips of the leaf then takes over.
N deff. start on the whole leaf,,,not just the tips
