Hasn't failed so far, Everytime I hit week 5ish my plants start to die at a alarming rate. I'm in a 5x9 tent with two 1000 watt air cooled hoods, trying out heavy 16 nutrient and in vermafire soil. I just recently noticed a white powdery mildew on my oldest plant, sprayed it down with a product that I cannot remember the name of right now cause I'm not home. And two days later lower branches look like there dying at a alarming rate, will post pictures to this in the am

Get the moisture down in your grow space - one common way is to get a LOT of air circulation. Products that contain soap as in Safer work well on White powery mildew - Thing you want to do is a two way attack.
When I had it I used another product a week after 2 treatments of soap. Use a different products not attacking with soap - get the concentrated botle to save a ton - Those spray bottles go for 10 buck a piece. Get the concentrated if you got the money - You'll also need to buy a dollar sprayer or better - Get a decent sprayer - They come in handy with growing...

Don't know what you used to spray as you forgot the brand... The products I'm talking about don't harm the plant a bit - The Safer Soap has stuff in it that actually helps the plant to heal.

When watering plants avoid getting leaves wet... Don't use any feeding that is foiliar or sprayed on the leaves.

Don't spray that stuff on your plants anymore until you sort this out. You've spent considerable time, energy, and money in this. Sort out your problem before you suffer any furthef damage. ID your misstep, make a course correction, grow yourself some wicked ass fire that you've b be en working towards.

My .02? You might need to take a hard look at your environmental controls. In a perfect environment you shouldn't need a spray at all. Find out why you do. Make your work payoff.

Add a uv bulb, add more air circulation and reduce humidity will help prevent mold and pm.

From those pics I'm not seeing mildew so you may have licked that problem. Looks like the leaf curling is the next thing to address. I'm guessing that is due to heat stress and not enough circulation... Those plants are pretty thick in there...

"Everytime I hit around week 5 my plants start to die at an alarming rate"

@William420 Sounds like a salt build up/lockout/burn. I know Vermifire is very "hot" (tested it for a large Hydro chain), so if you are using Heavy 16's recommendations from their feed chart every watering, you are giving too much. I'm always testing mediums/amendments/supplements (because I'm on the constant search for "better"). I liked Heavy 16's results, but nothing I've come across is anywhere near as good as my own.

Anyhow, if you want to stick with Vermifire I would "rinse" it. Depending on scale, that may be easy, or an indomitable task (I use way too much "dirt" to do this). If you cannot, I'd look at Ocean Forrest or Happy Frog.

The nutrient issue is playing into the PM. Your plants are unhealthy and therefore cannot fend off the attack. True, humidity does aid in the spread of PM, but if your read up on white powdery mildew you will find that the conidia (spores) are unique in that they DO NOT require moisture to germinate. This means that regardless of the humididity, the spores can and will infect your plants. Healthy plants have natural defenses against these attacks and "proper" sprays will boost the plants immunity as well as destroy the conidia. Don't spray your plants with anything that you would not be able to drink without ill effect.

Resolve nutrient issue, avoid excessive humidity levels, and spray with a "healthy" mix, you'll be killin' it in no time.

My humidity is consistent around 50% is that to high, and the heavy 16 is to expensive for me to keep having problems, I've been thinking about switching to all Fox farm I heard it's a little more forgiving.

50% is fine (at what temp?). Heavy 16 isn't the issue (one of the best lines I've tried VS my own mix). How many times do you water within a week? Any other supplements outside of the H16 line? Are you using the complete lineup? Are you mixing the supplements in the order recommended? How much water per plant? Container volume (soil)?

I'm watering daily, feeding once a week, full line up . I tried the foliar spray my plants really didn't like it. And mixing like the chart says, and feeding 1gal per pot plants are in 7 gallon pots
