haha far from any master over here
ffof if its ocean forest or happy frog it should have enough amendments in it to last you about 2-3months just water imo....it says its got EWC and guano and crab meal etc... most soil fresh out of the bag if made well with a top dress at flip should hold plants for a full cycle, also imo.
so you could easily switch rn at low cost if you wanted to with a compost tea once a week with LABs, and either recharge or some other microbe inoculate.
just an example of a base water schedule I've adopted that's working amazing
Monday - (water at 5% of total medium volume 10g pot = .5 gal)
Tea day (compost, EWC,FAA/fish hydrolase)
Kelp
Alfalfa (stop in flower)
Molasses
LABS
SST (barley and oat in veg, alf and corn in flower)
Tuesday
No water/plain water
Wednesday - (water at 5% of total medium volume 10g pot = .5 gal)
Plain Water (can add agsil16 or big6 if wanted no need)
Thursady
no water/plain water
Friday - (water at 10% of total medium volume 10g pot = 1 gal)
one of the inoculants below....
recharge
mammothp
fish shit
rootwise
etc
Saturday
no water/plain water
Sunday
no water/plain water
so really the days between my main water days every week also say "plain water" are just incase any plant might be in a stage where she's drinking a lot and needs more water between her scheduled watering times. I usually do less thank 5% just enough to get them to their main water day. of course feed more if you notice more yellowing etc... when I say feed I mean compost tea, kelp tea etc but if I need to give my plants a good quick boost fish hydrolase works really well, Neptunes has a nice NPK (2-5-1) ratio for the entire grow for me
I never have to add any cal mag but to be fair it gets added by the micro nutes that are in the top dress I use as well in some teas.
so im not 100% sure what's going on in your soil rn but I'm also almost 100% positive that you could fix it with a week or two of the above even if you only had recharge or some other kind of microbe inoculate.
they will help regulate, your soil that fresh should have enough cal in it to get you to mid flower if not the end, I say that mainly bc its so fresh and your already flowering in it etc...
with your distilled water you esp don't need to PH bc its very unstable due to the lack of PPM... there more science explanation but basically the lack of PPM/elements/ions allows it to be influenced and changed really easy... that's why it takes me like 1 drop of ph up or down to change the ph of distilled water... that being said it should morph to the PH of your soil which should be around 6-7ph right out of the bag... I think the soil I use is at 6.1 from their tests...
no runoff means no leaching... everything stays in there and morphs...
you can make it work with what you have and it will def work...
you can grab a few living soil fabric pots (15gal min takes 2cf pet pot) and never have to take that soil out ever again if you do it right....
fill the pots
add 50-100 worms (worms can make their body weight in castings per day, they also double their population in 90 days)
top dress with ewc/compost/bokashi
cover with barley straw
water with the above
top dress with etc/compost at flip for flower
water with the above
harvest
top dress again
cover with barley straw
replant next to old root stock
start from beginning
I use a lite soil, form BuildASoil... and then do the above... vs buying an already mixed water only but that would work too... just after every harvest reamend etc..
if you wanna keep it long long term like years then a soil test after a year or two to check levels and get more detailed on what to add comes in but im not even there yet either...
ill look at some more resources that rlly helped me
if you have the space to keep the MAC mom she would do amazing in living soil...
imo its less work...
I mix water, train plants, stare at them, defoliate, pretty low work haha
thinking of moving to BB, wanna get in on the marketplace but do you have to complete a grow log form what I understand?
