To cut my point short I was referring to his question directly regarding nutrients and feeding.
Obviously what I thought when he asked the question was I was under the assumption his environment is ideal and he is using good lighting and good genetics.
The main factors in resin production are lighting the source and type, and the environment including temp and humidity which all play a role in trichome production. I was assuming all of these things were good. So I answered the question taking these elements into context by explaining that he should look at what he is providing the plants for nutrients. And yes potassium silicate is directly responsible for resin and trichome production including bud production and plant health.
By week 5 your flowers should be covered in a good amount of resins and trichomes regardless of the variety. I have never found a strain that I dont have resin by week 3. But this is because I have a dialed in room, good genetics and good lighting (I just figured this wasnt his issue) so I focused on nutrients and feeding. I find that a majority of issues regarding trichome production and lack of resins and trichs is from over feeding or under feeding base nutrients. Simple shit like that goes along way.
