I added abt 1/2 a L of ice last night and this morning. I put 3 water bottles and a 2 L bottle in the freezer to start using in rotation. I did some research and it looks like I can pick up a used mini fridge for about $30, then run tubing through it back into the res to be able to reliably keep it cool for ~$50.

Yes I have seen that but a cheap diy option that is better is modifying a water cooler, like the drinking type. You can find videos online. I have never done it personally but you can use them with a temp controller so it will literally cool to temp then shut off until needed. You cannot do this with a mini fridge.

I feel like they are starting to look a little better but that could just be me being optimistic.

I am new to growing flower but I have used aeroponics extremely extremely successfully to grow almost every other plant possible from lettuce to orchids in aeroponics over the past 5 years. That is what swayed me into wanting to try it for flower.

Did you throw 15 bottles at those and foliar with 11 things stacked on top of each other at the same time?

I feel like purple discoloration is gone and the rust spots have not increased at all. I apologize for the shitty picture. Since I’m using blurple lighting in a grow tent my only source of light in a picture is flash or the horrible hues. I opened the vent in the back of the tent to try and increase air flow. I have had a small fan inside the tent since day 1 and I have a 6” duct fan blowing air in and a 6” in duct fan sucking air out. The air temps our out of my control to lower sadly. The res temps I am 100% going to be trying to maintain with ice till this weekend when I can build a chiller of some nature.

Day 21:
So they are starting to produce a light smell. It’s definitely sweet and fresh with citrus undertones. I’m assuming that’s good. I got water temps down to about 70 and they seemed to be doing a lot better. I implemented a diy water chiller but it isn’t running to its full potential yet. It seems to be able to maintain a temp but not lower a temp rn so I had to add ice back in this morning to get the temps back down. It appears to have a Cal/Mag lock out at higher temps (I think at least). I notice the purple discoloration in the stems at higher water temps.

I’ve noticed that each plant has some different shades of green on it. Dark green and bright green seem to be the trend for the most part ( assuming that it’s old vs new growth). But is the dark green too deep? And is the bright green to bright? Also, one plant has what appears to be washed out leaves, there is a comparison between what to me seems to be a healthy piece of leaf vs what I am concerned about.

The plant appears to have a very mangled look since I fimmed so young there is a large amount of young growth underneath the old growth. I was trying to tuck the larger leaves underneath the smaller newer leaves to allow light to touch every leaf. I also trimmed the edges of a few large upper leaves to allow light to penetrate down to the bottom. I am hoping to get some longer stems soon so that I can spread the plant out in a ScrOG. Since, this is suppose to be a tall growing sativa and I have such a small space I am hoping to be able to fill the 2x2 tent with vegetation that is under 12”. I don’t know if this is will be possible or not. My initial hope was to be able to yield 1.25 per plant. For a total of 5 Os in 4SQFt. I have 48” from floor to ceiling. With a 4 in light which I can flush mount to the ceiling and 14” in grow chamber. So I have 30” for the plants and the light’s clearance.

Lastly, from looking at the plants I’ve notice strong differences in structure. How do you determine differences in genotypes and phenotypes from differences imparted from enviromental factors? I would not be surprised if I had two completely different strains.
