Can't get these brown spots to stop... maybe its not a nute issue?

Heres a few pics of a plant leaf from a female I have in flower right now. Seems to be happening to some degree on most of my plants, brown spots forming around the veins on the leaves. Its been progressing very slow and steady, so I've tried everything I can think of. At first I thought it was a mg deficiency, so I fixed that, then phosphorus, wasn't that either... soil ph totally balanced, and flushed and then fed again to reset the nutrient amounts in the soil to be sure. Starting to wonder if it isn't something other than a nutrient deficiency or burning? Haven't really had a problem like this before, not quite at least, typically there is more yellowing involved around the brown spots if I am having a nute issue.

Any advice here would be great otherwise I suppose its not much of a big deal with how slow the spots are forming. The plant is about 40 days into flower.

No thoughts? =(

Interveinal Chlorosis. - I jus checked the FAQ's section and It looks as if its 1 of 2 things. Ill start with Ozone, it also says Magnesium., but if you are not using an ozone generator than that's not the issue. Start with the Epson Salt, CalMag, or MagiCal

Check this out: Text (Ozone Damage - Figure 8)

What amounts of epsom salts do you use? And how do you apply the salt? I've been curious how other people do this.. I just add it to the soil in solid salt form. I've heard some people crush it up and dissolve it in water perhaps?

I dissolve 1 tsp per gallon of water (luke warm), no need to crush it, just mix Epson salt and water vigorously, then water. You can add the salts to your regular feed schedule as well. If you don't see a change try SUPERthrive: SUPERthrive | eBay. Shit works miracles! 1-3 drops per gallon once a week or every other feed! AHHHmazing!

Gotcha. As for the epsom salts, that is how I was doing it recently, before that I was applying the salts directly to the soil. Question I have is.. how important is the water temp to dissolve the salts? I've been using cold water and I realize now I've been reading everywhere to use warm water, I've just chosen to ignore that advice for some reason up to this point lol. Hopefully cold water can still completely dissolve the salts? I'm guessing it just takes longer to dissolve the epsom salt, I can't think of any reason why cold water would cause something to not be soluable in water.. who knows, I'm always surprised by something..


Also with the superthrive... I'm pretty sure I've heard of that before, can you explain exactly what it is a little further? Trying to figure out how it would work out with my nutrient/feeding materials/schedule, but I can't seem to find a chemical breakdown of the ingredients and nutritional facts. I'll have to check my shop for the stuff to see if its available to me.

My leaves do this late in the cycle after Ive used Gravity. I dont really stress on it because the plant finishes wonderfully. I always looked at it like a chem burn. I add extra b vits and cal/mag for stress. Superthrive is basically a b-1. I prefer a b vit in the hydro world because Im in rookwool but there is certainly nothing wrong with the product. I dont think it will reverse the spots but slow/stop them. Hope this helps!

I appreciate the response, and that is kinda what I figured too. I haven't really thought about it that much since I've had so much going on lately but its actually time to start flushing that girl out for harvest anyways. As for the super thrive, I just noticed today that it is for sale in my garden shop, so maybe I'll pick that up one of these days and try that out.
