Dried up trichomes.

I've never heard of this method, but I will definatley try.
But I think it's too late for growing now. Well, who am I to say that. Do you think I could start growing in september? I understand the yield will not be huge, but still...

That does not look like bud rot to me (for what that's worth). Bud rot usually starts at the inside of the bud and is a light brown color (IME).

That looks more like nute burn. And, based on the appearance of the leaves, I second that. Notice how the brown seems to start at the tip of the bud and looks like it's working it's way inward.

Hmmm that's true. it does look different from the grey hairs.. although I thought that the rot affected the others parts of the bud like this (as in, before it worked it's way to them). So what do you think about the flushing? and growing in september? Thanks for the replie.

Unless you live down under, its pretty late to start a grow outdoors. I suppose a fast auto or something might work. I have an acquaintance who just moved his vegging plants outdoors to finish but they are 12 weeks old already.

Bud rot and nute/pH issues.

They won't regenerate. Increase airflow and ventilation and get a digital pH meter to keep them in check if you don't have one. If you have a quality pH meter they could be overfed.
