Rust, anyone have experience , how to prevent

[tintala]

So the last 3 grows have had problems with rust,it took over my last grow, and now is coming back. I am using 2k hps, in waterfarms, growing blueberry, in its 5 week flwrng. Seems like the older leaves get these black and rusty blisters and its slowly spreading.

I keep the room very clean, I do clean it once a week, disenfect, and vaccum. Not sure how to prevent or get rid of the rust.. Does spraying with baking soda really help? or perhaps I should just leave it be and let the plants mature til the end in about 3 more weeks.

Thanks in advance.

rust, how many of you have had this and been beaten by it? lots i bet!!!
first, rust is a fungi. it is opportunist. it preys on unwell plants. if something is a miss, rust is a sign. rust has been identified to have 7,000 species. it attacks crops of every description. but we're only interested in one variety arn't we?
if rust is present early in a grow, you have problems as it's an indicator something in your room is a miss. usually ventilation. go through your system and double check things are in place and working properly.
rust is an air borne fungi. if given the opportunity, it WILL take hold. it usually does during flower as this is when the plants immune system is at its weakest as its energies are concentrating on re-production, not survival.
depending on what part of the grow you get it, you can cure/minimize it with either chemical or natural remedies.
it enters the leaf via the stomata and then it's off and running.
fungacides used are generally copper based and include; thriram, manzecob, maneb or zineb at 10 day intervills.
organic;
baking soda, 1 tea spoon/ quart of water. spray on.
copper sulphate, read lables.
fungacidal soap sprays;
garlic sprays, 1/2 cup minced garlic, 1 quart of water. let sit 24hrs, strain, spray.
sulphur, one of the best natural sprays. it is low in toxicity.
micro kill, a citric based killer. i use this with great success
