800w Skywalker, Sour Diesel, Diesel Ryder, Purple #1

Wats going on stoners, well i have 2 skywalker feminized seedlings, 1 sour diesel reg seedling, 1 Purple #1 feminized seedling, and two diesel seeds reg Under a 400w hps and a 400wMH. They are all about the same age 2 weeks into seedling growth. i have questions about light spacing and fertilizing. there in 3 gallon pots with fox farm ocean forest soil. temps are between 80-87 with a rh of 45%. watering with plain water about every 3 days. When to fert the ryders and how much to fert the others i hear sour diesel is a sensitive plant so any replies much appreciated thanks. I will be keeping updates and pics about every other day.
