Okay, that makes sense about seeing the nute burn in flower.

And I really don't have time to go into details, but my experiments are basically just that--trial and error. 4 in one type of soil, 4 in another type of soil, 4 I've been putting pH down in, etc..

I'm just trying to expedite my errors is all.

They actually were inside. I put an air conditioner in that room and ran duct work from it to under my hood. I switch it over to just fan (so it pulls fresh air) but I guess it was just too cold still.

Even before I read about cold locking out phosphorus, I was noticing how cold my soil was at night when I watered.
