Setrile potting soil is an unknown you dont want,and your ratios are off .
If you want trouble free proven mixxes and nutrient amounts .
Read the first page of Organics for Beginners thread .Those recipes have been tested and are proven winners .If you have questions about the mixxes you can ask there someone will always help .
Sometimes the Organic Section reminds me of a sort of Horticultural Bible where self proclaimed prophets profess doom and gloom if a Sacred Recipe isn't followed to the letter. IME, size of container, what/how/when you feed, strain(s) being grown, amount of light, other environmental factors (amount of CO2, temp/humidity, etc), plant density (# of plants per grow area) are as important as actual grow medium. There are many "correct" ways to grow. Just my 2 cents....
BurnOne knows his organics. He wouldn't steer you in the wrong direction.
I've already posted your answer in the "Organics for Beginners" sticky. I did all that work just for you.All he said was "No.". Thats not very much steering, but it kinda helped...
Is this a good soil mix?
