Been having this problem for about two weeks. It started at the bottom of the plants with the older leaves. There is a yellowing all over one of the strains, the other strain seems a little more resistant. I am growing in a soiless mixture, indoors with Fox Farm. I am using a thousand watt HPS, with co2 enrichment. My last crop was affected the same way, but I thought it was do to the heat. I had a problem with the temperature while trying to get the ventilation right. Anyhow, if you look at the plants in the foreground of two of the pics, you can see they are not affected in the same manner, yet...
The younger plants are at 1 1/2 weeks. Any help is appreciated. Thanks.

this is normal for the end of flowering. the plants are using up the stored food in the leaves with a last attempt to stay alive.

do you plan on flushing the plants soon ?

I am using Fox Farm big bloom and tiger bloom according to the feeding table provided on there website. I have been growing these strains for a few years before I moved. They are bullrider x afghani and CA orange bud. They never exhibited yellowing leaves like this accompanied with dry crispy brown leaves. Thanks.
