Dude, looking awesome man. How many grows do you have under your belt? And critical kush, is that a cross between critical mass and a kush? Critical mass is supposed to have, well, the critical mass of buds that the plant can hold, so they are supposed to be bigger. But yours look fine, if you still have another 20-30 days of flower.
Those are looking seriously dank man, I hope mine turn out like that.
