(If you're not familiar with my epic saga trying to keep my plants alive during flower you can read about it here: https://rollitup.org/t/is-this-tobacco-mosaic-virus-almost-three-straight-years-of-total-crop-failure-should-i-nuke-the-grow-op.1085897/ )
I'm going to do a complete flush and feed tomorrow (sun) or the day after to ensure I'm not over-feeding and/or there's not an over abundance of something that is antagonizing uptake of other nutes.
Stats:
-16 days into flower
-Plants ~3'6" tall
-Buds have just set
-Leaves on three plants showing signs of phosphor and/or potassium deficiency
-8' x 4' cabinet
-2x 600W HPS
-Temp 80 lights on 75 lights off
-RH 40-50 %
-See pics below
Nutes:
Jacks Classic All Purpose 20(N)-20(P)-20(K)
Guaranteed Analysis:
Nitrogen: 20.0 %
Phosphorous: 20.0 %
Available Potash (ie Potassium): 20.0 %
Boron: 0.02 %
Copper: 0.05 %
Iron: 0.10 %
Manganese: 0.05 %
Molybdenum: 0.001 %
Zinc: 0.05 %
FLOWER FUEL Super Premium Bloom Booster 1(N)-34(P)-32(K)
Guaranteed Analysis:
Nitrogen: 1.0 %
Available Phosphate: 34.0 %
Soluble Potash (ie Potassium): 32.0 %
Sulfur: 2.1 %
Boron: 0.03 %
Molybdenum: 0.0006 %
I also have some raw (pure) mono-potassium-phosphate and some mono-ammonium-phosphate that I can try but I have never used or experimented with them.
I'm in 3 gallon soil pots. My plan is to flush with 9gal of water each, then feed 1gal with the following nutes (this is what I usually do at this stage, and it always used to work but it doesn't anymore):
Jacks Classic: 3/4 teaspoon
Flower Fuel: 1/4 teaspoon
Is this too much, not enough or juuuuuust right?
TIA
ps: Holy smokes batman I just realized by doing this exercise that there's no calcium or magnesium in any of my nutes! Isn't calcium and magnesium important for cannabis plants, or is the demand for those specific micro-nutes negligible during flower?
