Yellow Veins? (pic)

I just noticed this today and it's only on a couple of the fan leaves on one single bud. The plant is about 3 weeks into flower, it's growing in FFOF, its watered with either striaght RO water, or fertilized with Earth Juice Bloom. i nuted today with a 2 tblsp/gal dose of EJ Bloom. Once i noticed this leaf with the yellowing appearing to start from teh veins instead of vice versa, I flushed the hell out of it with RO water.

It doesn't look like a classic nitrogen deficiency, was thinking maybe Mg or Zn? If it's Mg would a foliar feeding of epsom salt be in order?

Thanks

looks like maybe a nitrogen dif

It looks like that picture was taken on January 1, 2006, and that plant is already dead.

lol, i just replaced the battery and didnt feel like resetting the time and date.

I also have the same problem with my leaves. I dont think its a nitrogen deficiency. Any other comments would be great

sorry i tried looking it up, i can not find anything.

what is the ph and room temps? Also I noticed the other leaf off to the side with a burnt tip and yellowing maybe a better leaf to go off of since it is more progressed in that leaf? what are the ppm?

necrosis for sure... you need mg. could be zinc or mn also but more likely mg.

ok i did find a few things that point to a mg deficiency

ya, i started a foliar feed of 1/2 tsp epsom salt to 32 oz. of RO water, we will see how that does...The other leaf in the pic was one of the original fan leaves and is just an old sumbitch. Almost all the leaves have a slight tip burn becasue i was seeing what the maximum dose of EJ Bloom the plant could handle, I found that 2tblsp/gal was a bit much and am going to drop it to 1.5tblsp/gal. I will also give it a small dose of EJ Grow on its next water to give it a bit of N, just in case. It still has over a month of flower to go so I don't want to start losing leaves due to a possible N def. quite yet. Thanks
