Hey sponge,

A few questions:
- What's your soil pH?
- What's the temp and RH in your grow area?
- What kind of plants, and what medium are they growing in?
- How often are you feeding them, and what exactly do you feed them?
- Please post some pix, like Irie is saying!

It sounds to me like a nutrient lockout of some sort, keeping your plants from absorbing what I'm guessing is Phosphorous. Check out this link for easy guidance, but also please post the above info as sometimes several different issues can contribute to the problem you're seeing.

I'm too inexperienced to give much advice, but this will all help others give it.

what strain are you running? It's normal for most strains to yellow on the main fan leaves a few weeks before harvest.
