Yes, i complain when i should be sharing my gratitude. Things could have been much worse, i am very fortunate that they were not. Grow shed is intact, house is intact, life goes on.
A very similar grow but with out the drama
I always recommend adding 30% perlite to all that FFOF soil,
diluting it some you can add your own nutes later
and makes germing a lot easier too
you are doing fine just you seed selection sucks, that can be fixed very quickly
I too grow most the year in a shed, but summer is outdoors, with winter closer inside
if to hot/cold IMO grow autos, keeping the photos for spring and fall
or like the auzzies grow at night, but in truth weed can take incredible temps
just we hold them to 27c/77f for greater returns
for your location understanding STOMATA is vital ...imo
allowing the plant to breathe free of ash, a foilar spray may help
good luck
ps avoid moss in your soils it holds water hence it hold nutes leading to nute burn
