Other than those two a the flip and to reset after harvest I use
Recharge
MammothP
Fermented Fruit Juice (from bananas)
LABs
and
Sprouted Seed Teas
Mammoth P? What ever for????
Simply brew your own bio teas! Talk about saving money.....
Build a soil is a great group. I find Kelp4less as another good organic source.
Technically I build all my organic soils myself. In such I use oyster and eggshell as the Cal source. Non roasted eggshell, pulverized in a spice grinder, can add some nutrition too.
Generally, I get confused by any "mineral" top dress. The reason being, is that any good built soil will contain enough "mineral" base to last a whole year of soil use - and not need to be reamended till that year of use.
Now Ca and a Mg source is part of any recharge to reuse it...
I also up pot several times to the "final" pot. This final pot soil is balanced to be bloom use soil. I have several formula's of it, for differing strain needs/wants.
NOTE: I spent a long time playing with living Bio teas and supplementing synthetic grows with it. This was being done for the sake of "knowledge".
To say that "living bio's" don't help or can't help synthetic runs? Incorrect! You can supplement high count living bio teas on an alternating schedule with feeding and
decrease your nutrient use by 50% or fry your plants. Not to mention that this nutrient was charted as an every watering use feed.
Not to mention that I have as a rule (and for decades),,Watered a metered amount everyday at lights on.
You might have to reduce the concentrations a bit - especially in bloom but, it works better to get more O2 to the roots.
Anyway, the amount of increased nutrient availability/use shocked me at first. It took a cpl of runs to balance the nutrient mix, and Tea use out.
No, I don't do it anymore. The by far largest style work I do is "water only", home built Super soils. Longer running strains and some that can be very particular/fussy. Do get some organic liquid nutrition later in their run, to supplement the soil nutrient availability.
All these soils are reused over and over. Recharge with what's required, when it's needed, and back into rotation it goes.
