some problems!! rust,deficiency???

[Andrewj]

So my set up is a 600 watt HPS in a 4.5x4.5x6.5 tent. I use A.N. Sensi bloom, Big bud, CarboLoad,Overdrive,Sensical,cannaZym,Nirvana,and
B-52. I use Sunshine mix #4 and add dolomite lime and extra perlite. When I first transplanted all my plants for coco to S.S.#4 I flush them a week later and got a pH of 4.7-5.2 and ppm of over 3000! I have gotten the pH down to 6.2-6.6 and TDS of low 600's.I am currently in week 4.5 of flower and this problem is spreading rapped! The strains I am growing are sour grape, Strawberry cough x Deep chunk, Three Purple Kushes, Three Querkles, 1 hashberry, 1 Lock Stock, And Platinum bubba kush"which I was lied to about the strains name" So if anyone can help that would be appreciated. And if any of you need more picture please ask. Thanks Andrew

Try posting in the infirmary. Sorry I can't help more, but plenty of people there will be more than happy to help.

Yeah, post to the infirmary first, but it looks to me like a Magnesium (Mg) deficiency.

But the weird thing is that Mg deficiencies are really, really rare.

I found this advice though so you can turn things around in case you haven't already gotten advice from others:

This can be quickly resolved by watering 1 teaspoon 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.
