How is your PH? It does look abit like early mag deficiency. This is from growfaq found here: https://www.rollitup.org/view.php?pg=faq&cmd=article&id=588

This can be quickly resolved by watering with 1 tablespoon Epsom salts/gallon of water. Until you can correct nutrient lockout, try foliar feeding. That way the plants get all the nitrogen and Mg they need. The plants can be foliar feed at ½ teaspoon/quart of Epsom salts (first powdered and dissolved in some hot water). When mixing up soil, use 2 teaspoon dolomite lime per gallon of soil.
If the starting water is above 200 ppm, that is pretty hard water, that will lock out mg with all of the calcium in the water. Either add a 1/4 teaspoon per gallon of epsom salts or lime (both will effectively reduce the lockout or invest into a reverse osmosis water filter.
Mg can get locked-up by too much Ca, Cl or ammonium nitrogen. Don't overdo Mg or you'll lock up other nutrients

Epson Salt is Magnesium Sulfate, so yes it will correct a Mg deficency. It also can effect your PH and PPM especailly when using nutes so keep an eye on it.

I use cal-mag and it seems to take care of it no problem. Make sure you mix it up good and get the ph where it needs to be.

the latest theory as to why I have these brown spots just hit me. My ro filters needed to be changed. I got this magazine called Maximum Yeild and I think it will blow your mind away. I cant type now about it. But I will post all I can find on their website later in the orgnanics section and just let all the + rep climb right into my pockett. Lol, anyway. . .

the minerals are slipping inand I have actually hardwater of sorts and by adding cal mag or even not I am really screwing up my plants. Simple, but the article is really nice. They got a 5 issue comparison in there between aeroponics in a rainforest and organic soil! I shit you not. They found soil to beat. Read more.
