My only problem with tea is scalability and the extra work I have to do to trirate my tea to know the big 4. NPKCa.
I reused our hydroponic base for seven years. Just had to be washed once a year.
As you know I like less moving parts. My perferd mix for soiless is metromix 510. For Canabis I would most likely use 510 with juveniles and my finish pots metromix 810 nursery mix. Really good for big plants.
Plants will grow to the size of the container. It is my second favor natural growth regulater and probably my first choice for canna. I don’t want any stress or until I decide.
I only have one big problem is coco fiber in the mix. It plays havic as a nitrogen sink in the grow. The coco fiber is trying so hard to break done it hold some of the nitrogen we feed. Basket growers have seen this for decades.
As for microrysi, I want them as part of my mix from day one this is why I like composted pine bark. It the best of the soiless amendment I have ever found.
I would bet any slow release calcium source is problibly a plus diatimatus earth because it is known to increase root hairs.
For feed you know my thoughts. Buy inorganic fertilizer and spend more time growing and less time cooking. Work life balance is really important. The last thing you are going to say on your death bed is “oh I should have worked more”
The people at Peter’s would likely give you the feed of your choice just for asking.
I would pic one of there calcium nitrate feed for the vegetative cycle and one of there bloom boosters for the preflower phase and the early flower phase slowly switch back to a vegetative feed and finish with no feed just clean water.
I want my one and only stressor in the grow to be the shift I say length.
