MC one part is so easy with
pop22 500-550 total ppm feed at every watering with a few select organic methods during flower, make for a VERY easy grow and quite good canna.
At that light rate, MC really doesn't harm the microbes or worms.
Just a casual observation, I think
Tattoochase has got caught up in buying and trying to use a large selection of products.
I really think he needs to step back and re-evaluate his grow methods. KISS is a very good grow method when first starting growing.
It's really easy to get caught up in buying a bunch of stuff and also
trying to use it all.
When this grow is finished, I'm gathering all my media in the totes and from the pots on this grow, combining them all on a tarp, mix thoroughly and get a soil test. I'll amend accordingly and let that cook while the next grow will be a simple Roots Organic Original (with DynoMyco mixed in if I see good results) with limited inputs of Recharge weekly, one dose of lobster compost when the plant is tall enough without leaves touching it, one dose of Craft blend at about 6 weeks and
J and Blue Gold Flower for flower inputs. Water would be tap with humic added at 1/4 teaspoon per 5gal thru the whole grow.
I've not tested my used media and just amended based on various recommendations. I've never done that when I had my huge food garden outside. When I finally found a place that would give a test that actually showed results beyond the silly NPK results, wasn't too easy to find in the early 90's, my production went up.

I'm not criticizing your methods. I just think ya need to step back and do some evaluation. Maybe a simple grow and concentrate on providing a great and stable environment based on the life cycle and let the plant do her thang. I think you might be amazed with the results.
