You sure that your growing the 'ICE' strain man....??? After viewing your pictures.. I'm really suspicious and it's got me really debating in my head of rather or not you have the correct strain that you think you have.
All the ICE grows I have come across... the buds are have shiny frosty trichs covering the entire thing... plus.. even the surrounding leafs (like the fan leafs that sit under the top buds).. even those fan leafs were frosted with trichs that have fallen off the buds.. or grown out of the leafs themselves.
I too currently have the 'ICE' strain. I ordered mine from Nirvana.. as of right now they're only their 3rd day of veg. So I can't really compare mine with yours as yours are pretty much done and ready for harvest. But once mine are ready.. (i've saved this thread) I'll come back and post pics of mine so that we can compare each others grows.. plus also that way I can prove my point about saying that I really don't think you have the strain that you think you have.
What phenotype are yours? You get your beans from Nirvana as well?
They still look lovely.. don't get me wrong. It's just.. they just don't look anything like any of the ICE strains that I've seen growing. We'll know for sure in around 12-13 weeks from now.. when mine are close to being harvest ready.
peace.
