Fastbuds - 2x Smoothie 2x Zkittlez Autos

1/23 (Day 36) - I look at the plants about a half hour before lights out, and the Smoothies look a little limp. Going to check them after lights come on, and then I will almost know for sure that they are 'sleeping' and the droop late before the lights go off isn't as detrimental as I thought. 1/24 (Day 37) - Start of the 6th week. Not much to note for today. 1/25 (Day 38) - Watered today, each plant given 1.5L. A few lower leaves were removed from all the plants. I feel like there is starting to be some discoloration starting on the Smoothies, similar to what I experienced last time. Not sure if they are just more heavy feeders than a mix soil provides, or if they just desire something inparticular, but it looks like I may encounter similar growth as last time I tried to grow them. 1/27 (Day 40) - Not much to note the last couple days. One of the days, I was only around long enough to take the pictures. The Smoothie plants are showing a bit of discoloration, almost just looks like they are more heavy feeders than the others, and seem to need more than just an organic soil to feed to the fullest extent. 1/28 (Day 41) - Going to water and likely pluck a few leaves from each plant tomorrow. 1/29 (Day 42) - 6th week is complete. Each plant had some extra soil topdressed (about an inch or so into each pot) since the original soil had compressed down a bit, and there was a lot of room in the tops of the pots. After doing that, the plants were then each given 2L of water. Removed leaves mostly from Smoothie 1, while the other plants only had a leaf or two taken off mostly. I didn't happen measure the plants last week, but this week, after adding a bit of the soil (might measure an inch or so 'shorter' than had I not topdressed), they are as follows: Smoothie #1 - 21" Smoothie #2 - 16" Zkittlez #1 - 17" Zkittlez #2 - 16" The plants range from 19-24" or so away from the light right now. I also flipped the plants, where the #1s were in the front and the #2 in the back, 1 is now in the back, and 2 is in front.
