Please understand i am not following any strict regimen, and this whole grow has been an experiment.

Ive been strictly watering with actively aerated tea's my whole grow.

About half thru veg, i decided to start adding GH gro, micro, bloom, and cal mag into my tea's, before brewing.

Ive been doing the 321veg, 123flower ratios. 5 plants, each get 3 gallons of water in their 10 gallon fabric pots. I dont even vaccum the runoff. It soaks back up into the pots within a few hours and my runoff is still testing great.

I notice my TDS readings when i add the nutes to the tea drop dramatically after a 24 hour brew cycle.

For instance- Todays feed, first 123 flower recipe:
15 gal tap water.... tests 150 tds straight from tap and 8.2 PH

ADD: 1 cup worm castings, 15 tsp Recharge, 1 cup molasses
40ml gro
80ml micro
120ml bloom
40ml cal/mag

Test again: 850TDS-8.6PH

Brew with 1150gph air pump for 24 hours and take readings again
130TDS.....6.2PH

Water plants with this mix TDS 130/PH 6.2 going in, TDS 320/PH 6.5 runoff

Plants look GREAT

This has been happening consistently.

So, are the microbes eating the nutrients, then the plants eating the microbes?

Would i be better off adding the nutrients right before watering so microbes dont eat all the nutrients?

Here are my plants at day 44 https://imgur.com/a/DPWKe

Can anyone make sense of what is happening in that 15 gallons of Tea?

TL/DR; Making Aerated teas and adding nutrients to teas. TDS after 24 hours of brewing dropping from 850 to 130, which is lower than what comes straight out of my tap?

Forgot to add

5 photoperiod plants-1 auto (surprise)
10 gal fabric pots-30/30/30/10 perlite, pro mix hp, composted horse manure, worm castings
4x4 foot tent
Gavita DE 1000. 6500k MH Veg-2000K HPS flower
temps staying between 66-81F, RH 40-60% depending on how recent they were watered
Watering with AACT/nutes added.... every 4-5 days as needed...
Vegged 45 days at 18/6...flipped to flower day 45, now on day 3 flower

Not a single reply? Well that's disheartening
