i am interested in the different feed numbers on the fertilizer labels. if you have finished a grow with a brand or formula you would like to brag about (or warn about), please post it up. specifically, i'm interested in the phosphorus ratio of the fertilizer. it seems that high phos fertilizers dominate bloom formulas. i was wondering if anyone out there uses a balanced or low phos formula with luck. examples of high phos fertilizers: 9-45-10, 1-3-1, 10-30-20 balanced ferts: 20-20-20, 1-1-1, 15-16-17 low phos 15-5-15, 3-1-3 so whats your middle number? what i've seen is most use a balanced feed in veg and a high phos in bloom. in recently looking at AN and Humboldt nutrients formulas, they seem to use balanced to low phos feeds. brand aren't important, i want to know the numbers you use and whether you will use it again or change.

examples of high phos fertilizers:
9-45-10, 1-3-1, 10-30-20
balanced ferts:
20-20-20, 1-1-1, 15-16-17
low phos
15-5-15, 3-1-3

so whats your middle number?
what i've seen is most use a balanced feed in veg and a high phos in bloom. in recently looking at AN and Humboldt nutrients formulas, they seem to use balanced to low phos feeds.

High nitrogen / balanced in veg and hi P in bloom, pretty simple.

well i thought it was pretty simple. but the more i look, the more i see its worth asking or trying something else. i heard that non burning black ash was a sign of too much phos. i started to look and see what favorite brands are and Humbolt looks like tops in most book. i did the math on the 3 part formula. veg wk1 3 - 3 - 1.7 v2 3.1 -2.3 -2.7 v3 2.5 -2.5 -3.3 v4 2.3 -2.3 -4 bloom wk 1 2.5 -2.5 - 3.4 b2 2.3 - 2.3 - 4 b3 1.8 - 2.6 - 4.5 b4 1.6 - 2.7 - 4.7 b5 1.4 - 2.8 - 4.8 b6 1 - 3 - 5.1 b7 1.1 - 2.9 - 5.1 b8 flush so in their infinite wisdom. nitrogen goes from 3% to 1% over the grow. phosphorus stays a constant 3%, and potassium rises from 2 to 5%.

i just did the math with Advance Nutrients 3 part. they use a constant NPK ratio of 2.3 - 2 - 3.7 i have never used either product, but these products don't use that simple high phos formula that we all believe to be true. general hydro 3 part ( this looks suspiciously like AN nutrients and humbolts' mixing instructions) vegetative 3.5 - 2 - 1.8 early bloom 2.3 - 2 - 3.7 late bloom 1.2 - 2 - 5.5

Hey Turf! Great question! My medium has been built soil-less with additions and and run with no ferts with the slight exception of fish emulsion at 2 - 4 - 0.5 if a particular girl needed a little booster. For a special and hopefully good run, I am using our future site sponsor Maple Reef Products "Love Potion". A two part grow and bloom formula. Will be using this in pro-mixX with Bio-tone starter from Epsoma and also in a flood and drain system designed by our own Tokecrazy. Peace! Pete N - P - K Grow 10 - 10 - 10 Bloom 1.7 - 10.3 - 5.1

i figured out Fox farm's 3 part formula too. v1 0 - 12 - 0 v2 v3 2 - 9 - 0 v4 8 - 0 - 0 b1 0 - 4.8 - 1.6 b2 0 - 4.8 - 1.6 b3 2.3 - 5.3 - 2.5 b4 2.3 - 5.3 - 2.5 b5 0 - 7.4 - 3.5 b6 0 - 7.4 - 3.5 these guys decrease nitrogen, raise phosphorus and raise potassium. i just figured out Jmansweed NPK ratios for Earth Juice. from the rates and numbers he posts in his fertilizer study. v1 1 - 2 - 0 v2 1 - 2 - 0 v3 1.4 - 1.3 - 0 v4 1.4 - 1.3 - 0 b1 1 - 1 - .8 b2 .8 - .8 - 1.2 b3 .8 - .8 - 1.2 b4 .9 - .6 - 1.3 b5 .8 - .5 - 1.5 b6 .5 - .5 - 1.9 b7 0 - .8 - 2.4

i am beginning to see a trend here. i think since phosphorus is more sensitive to pH, we can see deficiency symptoms sooner and over apply. i'm going to adjust my feed and give up my high phos bloom formula for a bit.

preliminary results of the low phos feed have been good. burn't ash has gone from black chunks to fine grey ash. this last harvest only had a short time with the low phos before flush but the end result burns 100% better. plants in the next rotation behind look tasty! IMO resin production and fragrance have improved.

Nutrients tend to be like vet bills and race car parts...you get what you pay for. Sure there are cheap nutrients that can get th job done but for the most part look to spend a little bit. Anythign fox farm, bio bizz, hesi, and humbolt will work wonders. personally i use good organic soil...just add water. i guess it depepnds on your preference if your growing commercial then do hydro. but if its for personal the extra 2 weeks itll take throughout the entire grow will rewards you with tremendous blues., yellows, purples, and reds come flush...not to mention that sweet sweet taste and smell!

I use this and "Bud Candy" starting in weeks 3 through the first week of flush (General Hydroponics "Flora Nova", Grow 7-4-10, Bloom 4-8-7).

Excellent results, like with Green Passion, I don't feel the need to go looking any further!!!

I use GH's maxigro 10-5-14 and maxibloom 5-15-14 in a flood and drain setup and they seem to work good when I have a little more experience greening my thumb I plan to start using different nutes to see what will work best for me and hope to try organic hydro someday

Too old and lazy to do it myself. I have been a huge Fox Farm fan for over 5 years. I have adapted the feeding schedule to suit my strains and love the results. I also use new FF soil mix every time I up can. Cost is around $4.00 per plant, but well worth it to me. Old soil is cycled into herb and veggie garden.

thanks for all the input. keep it coming. i was using a 10-5-15 veg fertilizer, and a 9-45-15 bloom feed when i started this thread. i gave up the bloom feed and just kept on with the veg feed through the blooming cycle. it has been improvement all around. the fertilizer wasn't the only change, but it was a big one. i'm not switching back.

ok don't shoot me yet...wait till i get it all down ..clone with azos...in veg plant success drench followed next watering with cyco xl, one with voodoo, keeps the gnats out, then maybe a karma drench etc...............in bloom once with voodoo. connie a and b...ignitor, big bud next overdrive last, bud candy, and bf-x..once a week karma with cal mag.....and I drench about three weeks in with insect frass. I LOVE the crystals with that stuff....it really makes the chocolope kush spectacular. I pinch most to four colas then keepem clean below no scrappy veg or suckers. The plants are using alot less water since I started cloning with azos. I think cuz they get the nitrogen out of the atmoshere as needed. Its quite the little microbe. I like quantum light on some plants but not the og18 cause it doesn't like nutrient push. ok take your advanced nutrient shots now. I guess I'm a sucker but I can't argue with 6-8z in four gallon pots under 600s. I nute about every 5 days with the a b and addons.
