you really need to get a scope dude and check the trichs. right now mine are cloudy, but i'm waiting for cloudy/amber... you need at least a 40x so you can see em. that's the only true way of tellin'. but, by the looks of the yellowing fan leaves and the lack of them (i'm assuming they all yellowed and died, which mine are doing now, i would say you are reallly close.)
oh and snip a few sugar leaves and check that way. it's hard to hold a scope up to a plant with a lot of movement....
