Organic Soil Test on Autoflowering

They are in full out flower mode and started to smell. All are ok in their respective soils and I am looking forward to seeing how they progress. I think the 1:0 soil stunted the growth a bit as it is still super dark green compared to all the others in the garden. However flower production looks nice and frosty and more advanced than 1:2. However I am sure that is just a gentic thing. The 1:0 soil is much thicker and I have to water much less than the others. I am sure it is not drinking as much eeither due to its size. I have grown in this soil before with photperiod plants so I dont think it is inhibiting root growth due to its compactness. The 1:1 soil is a mix of the other two so a little less watering and uptake but still an nicer size and nice and frosty flower. Starting to get concerned about temp though as it is going up to 28.5 now that I switched to HPS. I know this is still "acceptable" but since at night it goes to 17.5 that is a big swing..... Gonna see if i can come up with something to address this. Anyone ever have this much of a temp difference like that? I am concerned it is going to have a negative effect....
