Critical Kush (Barneys Farm)

I have officially started flowering on 9-25-15

I added a 13W UVB bulb. A very nice even flat canopy has developed however im still having a slight leaving browning problem pooping up ever so slightly only present on maybe 5 percent of the older fan leaves.

Looking good mate, she's thickened up heaps!
As for the browning, looks like it may have been nute burn, the new shoots look green though so i wouldnt worry too much unless it gets worse.

Interesting read. Where did you learn LST?

one of the best strains that Barney's has !!!!

looks much better
I who'd consider growing in soil at start. very easy to maintain.
