Strange leaf colors - Deficient?

Kcar · Jan 13, 2009

First time indoor grower here.
Serious seeds bubblegum
400w MH 24/7
Ebb&Flow
Pura vida Organics 850ppm

Looks like some kind of deficiency to me.
Any of you guys seen this before?
Looks like tiger stripes.
And some new growth is curling under...

Thanks!

According to this link http://www.icmag.com/ic/showthread.php?t=11688 it looks like it could be zinc or magnesium deficiency but honestly I'm on my first grow but have had problems of my own and gone to this site...found the link in the plant problems section of this forum...second thread i believe.

not sure but according to the FAQ on this site it suggests a Fe (Iron) def. maybe try the search function for posts? good luck!

I was kinda thinkin Mag deficiency.
Anyone see that?

it looks like it's affecting the new growth too. if that's the case, i'd say iron.

Should I throw some rusty nails into my rez?
Anyone know how to fix iron def?
Could it be a PH lockout?
Thanks!

check your PPM.
the super dark leaves look like a nitrogen toxicity, wich could be causing lockout.
cut your nutes to 1/4 what you are using and see if it corrects.
