Organic Soil Test on Autoflowering

I am starting to see a big difference between the three soil types. I doubt this is due to genetic variation but their is always that chance. The 1:2 mixture, which I am using with other plants right now, looks like it is best for autoflowers at the moment. The leaves have a nice green colour and not super dark like the other two. Growth looks great as well so far. 1:1 has a nice colour, leaves look like a good size compared to 100%TLO. Soil drains a little slower than 1:2 but better than 100%. 100% Plant is very dark green and leaves look skinnier than the other two. much smaller than other two as well. soil stays moist much longer than other two as well. So far it looks like 1:2 soil is working best for this strain of autoplants. as well as the other strains I am growing which you can see in my other current journal. I have only been giving water and will continue to do so for this experiment. unless I see a noticeable deficiency of some sort.
