hi, sorry for the delay in responding,
in flower i use 5ml of bio-bloom and topmax per litre,
with 4ml per litre of bio grow,
i also use 1tbsp of molasses per 5litre of molasses.
i have found molasses has improved health in my plants and has increased yields, but more so giving fantastic smells and flavours to the smoke itself.
i used to monitor ph quite closely when i first started, but so long as i use bio soil that comes with a 6.8 ph ready mixed, and perlite, and using standard water checked at 7.1ph,
the soil/perlite acts as a buffer making the need for me to test unnecessary.
i have tried hydro using the complete canna range and found it to be a completely different taste and had a reduced yield for me.
here's a few pics of my last harvest
