If you are looking to increase trichome production I use 3 products that have worked very well for me in flowering.
I use Snow Storm Ultra as a foliar spray at 2.5-5 millilitres per litre in flower every 7-10 days and discontinue use 1 week before harvest.
I will only spray Snow Storm Ultra just before the lights go off for the darkness phase of flowering.

I also use General Hydroponics Liquid KoolBloom and KoolBloom Dry in flower.
I use General Hydroponics Liquid KoolBloom at 2.5-5 millilitres from the start of flower until 3 weeks prior to harvest then use General Hydroponics KoolBloom Dry for 2 weeks at 1/4 teaspoon or 1.25 millilitres per gallon and discontinue use 3-5 days prior to harvest.
You can see these products in use and the results in my KingJohnC's Lush Lighting LED Dominator 2x Soil Indoor Grow Journal and Review.
