Plants loosing all new growth and leaves from bottom to half way up the stems

What generally causes this? They are under 400 watt HPS in beginning of flowering stage. I have them up in attic, gets up to 90 degrees alot. I have to water every day & ahalf. Ive got basins under them that will hold extra water.I also sray them with a mister each time I water. By the time 18 hours pass they have just about drank that water up and are beginning to dry out. I don't have a air flow system to my light. Wouldnt even know what to do. I have a 12x6 area enclosed up in the fully open attic with plastic for the walls and reflectix insulation bubble wrap over the plastic for better light reflection. Opened it up a little for some air flow with a fan. So will too much water cause them to loose their growth halfway down the stalk or too much heat and dryness? Is there some kind small portable cooling unit I can buy at Lowes or something? Lol Just to get temps a little cooler in there?

They loose alot of leafs early in flower, the plant is pulling nitogen from the lower plant to put up flowers.
It will stop after a bit. It happens. No biggie.

Just remember they wont need near as much water now cause the 12 hrs darkness.

Try freezing 2 liters full of water, an putting a cold one in every day?

Dont pull them off no matter what. I was cutting them off whenevr they looked yellowy at the advise of a few members, now i leave them on until they can be slightly tugged off (theyll be 100% yellow and shriveled)


This slowed my yellowing way down, where as cutting them off just made the plant feed on a newer leaf.
