Alot of weird shit going down under the 1000watt

I saw in the original post that he was using a Tablespoon of something, and a teaspoon of something else. If he is putting that much nutes in a gallon, then water his girls with it, that would explain the nute burn. The high temps and low humidity mean lots of water transpiration, and your girls are being force fed nutes. Whatever mix that was, try adding that to 5 gallons of water... not 1 gallon.
my grow is hot and dry, and weak nutes was my solution.

i just set it up exactly like that except, my vortex fan, (illustrated on the right) is sitting on the mother box and the only window close is the left side cause the box is pushed up against the window. so i stretched like 6 feet of ducting over the box and out the window. their air flow seems good. the glass on my hood is still hot. i just did this like 5 minutesa go so maybe im too impatient. i also placed 2 intake fans on the bottom. think itll work?

yes i should, but i was dumn and bought the wrong hood, i have a 1000wat hallide. it just doesnt fit. oh well. ill buy a bigger one after the harvest

pics of my setup/ ventilation

its set up like that guys drawing. so theirs no ducting on the left side of the hood to take in air from the box. the ducting you see is how i had to strecth it to get out the window. but putting my hand up to it, a good ammount of warm air is coming out. it is a vortex after all lol
