I have this "friend" who is a relatively experienced indoor grower.

Now, he has to keep a check on his girlies starting around the 4 week point to look out for hermies.

Some of them go to just about full maturation with no or few seeds by harvest.

However, many of them start to develop seeds at about the 5 week point.

The seed bundles usually start at the bottom of the plant and work their way up to the top. And, once they start, they spread like wildfire and here comes the axe!

He's understand that stress can be a major culprit; such as photo-poisoning, heat, lack of water...

However, might there be chemical or nutritional inbalances that may be to blame as well?

I've heard that you should go lite on the nutes toward the end of the flowering cycles.

What do ya think?
