I have a small magnifine glass to look at trichs but its only 10-15 x's so its hard to tell. I think they ae starting to turn milky but DEF no ambering. As far as strain, Im not sure. They are clones and from what i rememebr the strain was called "T" (maybe that was just an abbrv.) They have been in flowering (12/12) going on 7 weeks. The nutes are FloraGro(2-1-6), FloraMicro(5-0-1), and FloraBloom(0-5-4) (all used in conjunction with each other). I was told these were the top of line nutes to use. I recently added Cal-Mag(2-0-0) in small doses to help with the blooming stage (it was recommended, but not essential). As far as the flush goes, I was just going to turn off thier feed 2 days before chop. This is the method being used from where they came from. Is it necessary to flush, if so what do you recommend? thanks. also, ANY idea on timeline as far as how much longer they have to go based on pics i have?
