Bottom leaves turning yellow....??

[Heads4]

The bottom 1/4 of my plants, the fan leaves are turning yellow and breaking off with ease......

They are about 5 weeks into flowering and the tops and buds look to be in fine shape....

It just concerns me that my chem. levels might be off..

What do you think??

All areas that are now suffering from the late summer / fall light cycle will react accordingly. Those areas that get the least light are the first to go.

It will spread to the middle next to the main stem.

As long as the flowers keep growing, you could care less about the leaves :)

Harddon you the man...

Thats what I wanted to hear...

By the way i have a new blower installed...Looks exactly like the Dayton 265 on that website...

With my old weak fan temps were still getting to 90

Now with my new blower temps are at a max 86 and humidity is at 50

I appreciate all the input

I also have mylar on the way that all the walls and ceiling will be coated with :)
Then i will get the Hortilux bulb :)
