Medical Green house in the Midwest

20 Plants in 3' amended hole.
Hole amended with Alpaca Doo, Earthworm Casting, Sea bird quano, Bat quano.

Plants have been healthy until the past few weeks.

Plants were feed plain water with Alpaca Doo top dress during Veg.

At the beginning of flowering plants were fed a dose of FF Big Bloom.

Because of fly overs the lid is kept on the house, however all side walls have been removed and covered with weedblock to insure good airflow.

There are also 7 fans moving air including a barn fan pulling warm air out.

Plants began wilting on the bottom, So I thought over water and perhaps root rot.

Plants were then given mycostop, and allowed to dry out for several days.

Plants were water again with plain water.

Stems show no signs of redness or any unusually color.

However temps have been high with high humidity because of lots of rain. On hot days it's hard to keep the house below 90º

Tops of plants look fine.

Strains are:
DNA Genetics LA Women being hit some what hard.
Bubba Kush getting blasted dead leaves every day.
DNA RockLock, Not so Bad normal leaf lose.
DNA LA Confidential, getting blasted from the bottom up as well.
Swampy's Free Leonard, Local strain, No problems at all.

Plants seem to be dying from the bottom up.

I'm thinking it's the high temps and Humidity that's kicking my ass, Any help would be great!

The 2nd and 3rd pictures show a definite Phosphorus deficiency. But the question is whether there is not enough in the soil or is it being locked out. Thats what sucks about not growing in containers. You cant measure runoff Ec/Ph. But anyway you have a P deficiency. Dont worry about temps as long as there is adequate ventilation.

So you think I should up the hit with some P, I have some Roots Organics HP2 which is 0-5-0. Think a shoot of that would do the trick?

I think your right, because the problem did start with the unset of flowering, when P is most needed. Damn what a jack ass, too much on my mind!
