Wedding Cake & White Widow

We have reached the half way mark in flowering and the girls are blooming well. They are certainly getting thirstier, and I have moved from the 2 watering/feeding per week to a 4 waterings a week with feeding every other water. Nice sweet smell on the flowers, they are growing dense which is great and i don't have major concerns. Yellowing on tips hasn't got any worse after lifting the lights. I am still rotating the plants every watering (about 120 degrees each rotation) as I am using a combination of lights and want to avoid parts of the plants missing out on the good stuff.
