9/1/17
day 51 of flowering for the blueberry
aero res
ph 6.0
ppm 95-97
I changed the res today, new formula:
12.5ml mammoth p per 40 gallons
per 5 gallons
5ml protekt
4ml grow
1ml magpro
2.2ml ph down
which comes out to ph 6.0@68f ppm 95-97 with a starting water ppm of 9-11
Significantly less than my concentration was with tap water. Starting with 90ppm of tap using the same dose came out to 220ish ppm.
I made a spreadsheet to calculate the npk to get a ballpark idea of what my ratio is, I don't know if this is right but it seems to be.
I plug in the fertilizer numbers up top and then I can play around with different dose amounts, it adds it up and (everything in quotes is what I'm not sure about) "then averages what percentage by weight the npk ratio is".
