GG4 First Grow Ever

This is my first grow ever and it is so exciting to watch! I have been growing tropical house plants for 20+ years. Recently I have obtained my medical card and am able to grow legally, so I thought I'd give it a try. So much more rewarding than tropicals! This is my GG4 plant #1. She's been in flower for 25 days now. I am noticing the entire plant is turning silver from the trichomes? I have 1 pic where you can see the difference by looking at the bottom of photo. There is a bud site from #2 photo-bombing. Totally different color, yet #2 is only 3 days behind #1 in flower. Absolutely stunning to see these buds form before my eyes! I am grateful for forums like this that have helped me as a first timer to make the best of what I can. Thank you! I have been pruning, topping, and using LST method from veg. #1 currently has 94 uniform bud sites, this does not include the small bud sites. She is only 23" tall but her span in every direction is a meter. I can not wait to see what is going to happen next! I have no idea what to expect???, but I'm looking forward to it! Botanicare nutes, 20 gallon pots, purified water, and 2-1000 watt HPS.
