If you're growing organically and in soil ive heard many places not see the need or the difference in flushing. However seeing that you're using some bottled products organic or not i think at least a small flush would be good, it just may not need a week of flushing like other grows. You may just be able to slowly eliminate each product as you go towards flushing, I'd leave the molasses until last as its all natural and helps sweeten too. Then maybe just flush 1 or 2 days with good runoff. Happy harvesting ✌️
