you just gotta hang in there , I bet there are trichs on the inside of those buds ... the last pic does look better though . There is nothing I can think of to make it producemore trichs but a lot of peeps feed molasses when flowering - supposed to help with the trich developement but I doubt it waould acually add more .... good luck and just hang in there - it may suprise you in a bit. You cant follow the guidline times ... everyones setup is a little different and those are optimal conditions with some add spin to help sell seeds ....
