@UCMETOO here's the formula I ended up with.
3ml / gal
calimagic
4ml / gal gh
floramicro
9ml / gal gh
florabloom
That's a nutrient profile of 75N - 60P - 102K - 55Mg - 113Ca
I then also add
protekt at 3ml / gal which I think was roughly 30 ppm of K and Si. I ONLY run RO water.
Unlike what everyone on the forums says and what CC says, I always strictly run a more acid ph of 5.3-5.5.
I don't dump nutes every week, instead I go two or more.
Fresh batches are always 50% strength at 400 tds. I top off the system with a float and rez with RO. A good fresh batch will see tds fall but ph will stay the same. Too hot of a fresh batch will see tds fall and ph drastically fall with it. Too weak of a batch will see tds fall and ph rise.
On a good fresh batch, tds drops and ph stays the same for a few days..once the tds gets low the ph starts climbing to show plants are getting hungry, this is when I do my add backs directly into the epi center. I aim for 100tds over starting tds. So if it went from 400 down to 300, I add back to 500. I keep this going until I max out around 800 tds. So when 500 gets to 400 I directly add back to epi to 600. When 600 drops to 500 I add back to 700 and so forth. That's just an example however, I wait till ph starts to climb for my add backs tds is irrelevant.
I tested not adding back and observed ph climb to 5.9, top out, then tds stops dropping because the left overs aren't "edible" and ph drastically crash to 4.6 . think of it as a roller coaster or story plot line we learned as kids. Ph stable is the intro, ph climb is the leading events to the climax, and the resolution is ph crashing from no more viable nutrients
Exposition means good food, rising action means starting to get hungry, falling action means nothing good left to eat
Once I've hit my max I'll dump the system and start over with a fresh batch at 400tds and repeat the same procedure.
For my add backs I fill a home depot bucket with RO, add my Si which shoots ph up to 10.0. I ph down to 6.5 then add my base in . if I don't ph down the Si reacts and the second nutes are added they go cloudy from drop out.
I slowly pour the bucket into the epi center and done.
