I've never had an N tox in flower with Masterblend. I like 3 grams MB, 2 grams cal nit flower week 1-5. Week 6 is 3.6 grams MB, 2 grams cal nit. Week 7+ is 3.6 grams MB, 1.66 cal nit.
If you're adding MKP, I'm surprised you're not locking out magnesium with all that potassium.
I’ve been thinking a lot about your comment regarding locking out magnesium. I’ve been treating 3 of my plants for a calcium deficiency. Your comment prompted me to read a little further and look into PK toxicity. I think you might be right about locking out micronutrients, though not magnesium. I think the extra PK I’ve been giving might be locking out manganese and possibly calcium. So I’ll give them a good flush tomorrow and follow up with a balanced application of nutrients.

It's a balanced fertilizer. The American style of growing is to blast it with phosphorus, even though the plants only use available P, not absorb excess Phosphorus in flower. It only serves to cause problems with the plant. Cannabis is essentially the same nutrient requirements as determinant tomatoes, but they won't tell you that at the hydro store.

Hey Bill, are you not using magnesium sulfate along with the masterblend and Cal nit?I've never had an N tox in flower with Masterblend. I like 3 grams MB, 2 grams cal nit flower week 1-5. Week 6 is 3.6 grams MB, 2 grams cal nit. Week 7+ is 3.6 grams MB, 1.66 cal nit.

I am, but I tend to do it as a quick-acting foliar with my LED vertical racks.
No issues with magnesium yet but I’ll definitely be on the look out for signs of lockout. I only add 1/4 teaspoon mono potassium phosphate 2 times per week. the strains I grow could be more sensitive to N.
Hello brother.
I'am sorry to ask this, but could you explain to me: 2.5 gm Potassium sulfate+ 25 ppm fulvic acid for flush ??
Why adding Potassium when flushing. Could be a really noob question...
What are your recommendations in "VEG" i'm currently using your flower dosing hope all ends well without any extra additives, was thinking of adding flower fuel but seen it may not be needed. first time using MB. And is there any suggestions on feeding schedule in coco. I currently feed once a day even if the coco is still wet does feeding multiple times in a day have any benefit?It's a balanced fertilizer.

I'm misremembering. CALCIUM Potassium is the see-saw, not magnesium. Most people fix it with cal-mag. My brains not always good at word thinkin.
Potassium controls the water balance. Sulfur makes them smell good. Fulvic helps use up the remaining nutrients. It's my homemade version of Heavy 16 Finish.
I am new to growing but I’m running nine plants on Masterblend. I’ve just flipped them and I’m going to flush and make a new batch of nutes. I was going to us a MB mix ratio of 2-2-1.5. I also add Potassium Silicate, and KoolBloom. I’m getting so many different opinions on PH but was going to target a finish PH of 6.2 and an EC of 1.00.HiI would start to phase out the calcium nitrate soon. I find plants start to develop N toxicity if you keep on feeding the calcium nitrate in flower. But since you’re eliminating the calcium source, you need to keep feeding cal mag through the rest of flower.
In flower, I feed 1/4 teaspoon tomato and veg and 2.5-3ml of cal-mag per gallon each feed. Twice a week I add in a bloom booster (mono potassium phosphate).

Thanks for your answer. Im also interested by your VEG schedule with MasterBlend.
Thanks Bill
Hi Bill,
What is 25 ppm fulvic acid for flush?
I just purchased the 5 pound of Potassium sulfate online. Is it 25 ML of Fulvic acid?
Thanks
Grams per gallon to parts per million calculator
1 gram per gallon is ~250 ppm. For simplicity, 1 gram to 5 gallons is 50 ppm, which works fine like wine. As long as it's not RO/DI water in flush, you're good.
