trichomes have a salty structure and are falling off

Your feed amounts are wrong. Plant has nitrogen toxicity, and that likely messed up the flowering process. Flowering npk ratio is 1-2-3. So very little nitrogen is needed in flowering stage. The darker the shade of green in leaves tells you how much nitrogen is in the plant. Slightly darker then a lime green is ideal amount. Toxicity is dark green, Shiney leaves, and clawing is another sign. There is nothing you can really do beside harvest when it's ripe. Which looks to be very soon if not there. Looks like it is trying to fox tail as well. High temps can also destroy the trichromes. 82F is max they can handle. I would start a flush, and turn light intensity down . Keep room temperature in range. Then harvest in a week.

You are feeding waaaaaaaaaay too much, this can have a negative impact on flower development and trichome quality. Other than that, genetics of the individual seed plays the most important role.

Looks pretty normal to me mate some genetics have a lot of variation between plants you get some good ones and some not so good luck of the draw
