Bio bizz nutes in sunshine

Hey everyone. Couple questions and things going on over here.. We run bio bizz full bottle line in sunshine mix #4 in 7-10 gallon fabric pots. We have led lights and drain to waste tables. We go by the bio bizz feed chart for inert media growing. We feed bio bizz every watering for the most part. We water in until full saturation but not much run off as they advertise.. Plants once established tend to want fertigation every day to every other day. They get big (tall) by the end of a run. We run 80 plants at a time and our grow room is dialed at roughly 80f and 55ish humidity. 800 umols-1200 umols on the lights at canopy and we ramp up to 1200ppm of co2.

questions are, is anyone else here growing similar? Bio bizz and sunshine? We tend to see what appears to be either a lock out or under/over fertilization at around week 4. Assume over fed maybe vs under. Brown spotting, lighter green colored leaves at the top of plants but darker green middle to bottom and sometimes yellow tips and bluish/purple leaves. We use filtered water and organics alive calcium and organics alive micro 7. 1-2ml each per gallon. Added some pics.

I use there grow bloom and all mix its light on calmag other than that its great stuff just remember you have to use both all the way through not just bloom in bloom and veg in veg as organic bottles go you wont get much better once u get the hang of it i use indoors and out but i water till run off and there chart uses too much ime

Yeah we’re not using the all mix or soil which I think is part of the issue. We use both grow and bloom in flower as they recommend. It seems high in nitrogen though and low in phosphorus when studying the NPK and experience using it. I think the chart is high in doesage as well now even for inert media. What’s your go to dosages for all mix? You running like half strength bottle amounts?

Im from the uk so the formula varies regionally with biobizz i heard so a standard weaker feed id do here would be 1ml of veg and 1of bloom into two liters of water as you said you will need more cos your medium so id work it up or down 0.5 ml till you happy with it depending on what stage of life dictates what you go heavier on and outdoors i run jacks magic compost mixed with some bio bizz all mix i never grow in anything but dirt i prefer its simplicity vs hydro

Would you be willing to tell me the NPK values on your bottles stickers? I’d like to know how different yours are compared to ours in the states. Thanks for the reply.

our Grow bottle is 3-0-7
Bloom 1-2-2

A lot different. I’d prefer your formula. So in theory we’re running 5-2-9 NPK and you are running 6-10-10 in flower (12/12.)
I see yes bud seems so thats a bit different from what ive heard the uk and euro is same formula but usa and Australia have there own formulations

You would think because the formulations are different they would have different feed charts for certain areas. Bio bizz isn’t really that helpful when we reach out to them unfortunately..

I don't think the npk titration of their fertilizers really changes from country to country. I had asked the same thing of another Dutch organic fertilizer company and the answer was: "Local law often forces us to have the product analyzed at a local lab, and test results can differ".
more... "It’s all made in Holland to exactly the same formula. It all comes down to lab testing. It’s very hard to get accurate testing with organics. Most countries ask us to supply local lab testing for guaranteed analysis, then in the ratio from the test has to be the ratio on the label. Hence the different ratios"

also keep in mind that the npk titration shown on the label, especially for some EU countries, does not correspond to the real percentage of the individual elements. To give an example, in Europe the label of the same product reports npk 18-6-12 (but P and K are oxides), while in Australia it is sold as NPK 18-2,6-10.
in the example above the titration 6 P indicates 6% phosphoric anhydride, not phosphorus. To find out what the real percentage of phosphorus is, it must be multiplied by 0.436, the phosphorus index. 6 x 0.436 = 2.616.
Same calculations for potassium if it is indicated in the form of oxide. The index for the potassium content is 0.83. So 12 x 0.83 = 9.96
So let's see how 12% of potassium in the form of oxide contains 9.96% of potassium, rounding off 10% which is what the label of the same product sold in Australia for example indicates.

Is this your feed chart? I know you don’t use gallons as a measurement.
I dont use charts ive used it so long its kinda fixed in my memory i use a modified version of oldtimer1s feeding schedule as its changed since he posted it if you google that an uk420 you should find it and your right its litres not gallons we use btw on a side note many use the fish mix instead of the grow to good effect just dont use both same time

Makes sense it be silly to vary it too much you would think i just heard folks elsewhere say theres is different
