First Time Grower, Longer Term Toker

Buds are fattening up. There's a real sweet fruity aroma that fills the air. The pistil on the top part of the plant have mostly turned orange and only about half of the pistils have started turning towards the middle/lower part of the plant. The trichomes are still pretty clear and light. Say have about another week or so before they start turning amber in color. Shooting for only about maybe 10 percent of the trichomes to turn amber before harvest. They are really drinking up the water now. I am refilling 12 quarts minimum for plants 1 and 3, while plant 4 is only getting about 1.5 gallons every other day. I may repeat this weeks nutrients levels if the trichomes are still looking strong next week before I start the flushing. The website says flowering time is 56-63 days. We are currently at 42 days into flowering.
