Not my first grow but by no means an expert...
I have a White widow Auto, from Seedsman. 11 weeks and 5 days. Looks healthy enough and never had any issues apart from when it was a seedling and looked a bit mutant, .....although the leaves have always been unusually dark.
The issue is I can't see any Trichomes, none !! .....and I expected to by this stage.
The LST has produced several fairly even sized and decent looking colas that are slowly starting to fatten up....but none of this amazing frosting I keep reading about.
It is a soil grow, using Fox farms trio nutes, extra bat guano/worm castings as occasional top feed, and molasses (sometimes) PPM on last measurement of run off was about 1400 (it had been higher a few weeks a got before I got a ppm meter.)
temperatures are high here, average about 33 C and humidity about 60%, but that was partly why I chose this strain as it is supposed to be happy in higher temps.
Just cut down (last week) a GSC Auto planted at the same time, in same tent.....with lots of trichomes.
is it just a question of patience ?...I have seen some grow diaries for this strain that go as far as week 16 before harvest.
