I don't follow what you're asking. I see two schedules, are you asking for the results of the Veg and Flow mixtures? Like, do you want to see what 50ml of PBP grow looks like in a gallon? Also, what are the veg and bloom NPK numbers above?, What do you want done with those?

it might be my imagination but i see a lot of recommended nutrient formulas (like Lucas or Greengene) running the same ppms and ratios straight through weeks 1 until flush with minimal variation.

on the other hand, liquid hydroponics companies seem to vary the feedings week by week increasing ppms as flowering peaks and then tapering off. specifically, i am wondering about how something like pk 13/14 or MOAB would fit into a nutrient salts schedule. they are usually only recommended for a week so is there any benefit to spiking the PPM of P and K for a short time, and if so at what PPM?

my bloom mix is already hovering around the 200ppm mark for K and i believe anything much higher could lock out other elements. i think MOAB gets the PPM of P somewhere around 180 whereas most bloom feed schedules keep it in the 100 range. does strategic boosting of these elements end up with better results than a consistent level throughout? or is the risk of redlining the plants production not worth it?

im using coco and it seems a better approach is to maintain ppms and simply feed more often, something im not sure hydroponic companies are tailoring their feed schedules towards....

I wish I had more space, I'd love to give SOG a whirl. For my spaces though, I require 1lb per plant so I veg for much longer and my winners get their own 6 COB fixture and room. The losers, well the losers get what losers get, lol.

I just veg them there the 6 7gallon fabricpot go under 1000watts hps in a 4' x5' grow space in a week for the final veg winter is comming need the heat next summer i buy another hlg550v2 to replace the hps lol and I leave 18 5 gallon pot under my led 2×4vl and 1 x hlg550v2 in a 5' ×9' space in the pic .

I found another bit of very useful information on 420. It describes how to calculate the density of liquid nutes to be used in Hydro Buddy, or math in general I suppose.

This is important. As you add salts into water... the water keeps the same volume (roughly speaking) but gains weight. So every bottle of fertilizer should also contain the net volume (liters or gallons) and net weight (kg or pounds). In order to accurately calculate the PPMs - we need this ratio. So here is the first calculation:

W/V% = Net Weight / Net Volume

I linked the quote to the post that sourced this info.

feed ratios.jpg Here is an interesting graph from Otoke Horticulture. They seem to specialize in "cannabis cultivation consulting", so I take it they'd have some measure of trustworthiness. Nevertheless this graph goes against much of what I've read.

Some puzzling things of note...

1. Week 1-5 flower is a higher nitrogen than in veg.
2. Week 1-3 of flower has no calcium. I don't know if they forgot to include it or they are saying calcium is not needed. Might be tough to get that much nitrogen without any calcium while using Calnit, so I think they just forgot it.
3. Week 5-6 of flower have eye-wateringly high PPM's of P and K.
4. Those high levels of P throughout the grow probably don't allow any mycorrhizae to ever take hold.

I found the graph from this link where it is explained that by having high levels of nitrogen throughout the grow, the plant puts on mass which can in turn use the supremely high levels of P and K to put on bud size as it peaks.

http://www.cannabisbusinesstimes.com/article/grow-bigger-fatter-plants/

The article claims "the best-yielding growers we’ve seen are consistently those whose media is crusted with dried salts in late flower."

Any thoughts?

I think i found the perfect mix for botanicare flowering321

CANT YOU RUN IT IN UR PROGRAM
one last time
10 gallon

Pure blend pro veg------ 80ml
Pure blend pro bloom-- 80ml
Calmag-------------------------40ml
Epsom salt--------------------10g
Potasium sulfate-----------1,5g

Instead of this i give 22%more ml after to get the cacul right gram vs ml like ur post say

so has anyone bought one of the "kits" from jacks? I got the "individual grow" kit(note-doesn`t come with Epsom salts)
and is anyone using the feeding schedule they give?...do I need to add anything else? fulvic, humic, prozyme, mykoo`s?
I`m growing in peat has perlite in it...and I`ve got well water...my well water ppm`s is only 110-120

I'm seeing great results when adding a fulvic/humic/kelp blend. So much so that my plants lap that shit out of the recirculating feed in about 2 days. What I mean is when I add it, the water gets very murky, almost as dark as Guiness beer, but after about 2 days, the nutes turn to the color of regular American beer, more or less. mycos are great too. If you'll read back a couple 10 pages, you'll see I went a direction of pinpointing ideal elemental ranges rather than sticking to a cookie cutter schedule as with other lines. I feel this has gotten me way more in tuned to plant language and deficiency diagnosis. The approach I took, I was able to tweak the composition of 6 components (excluding the organics) to produce near perfect feeding. I feel much more comfortable with the information that @im4satori shared with us than blanket claims of using Jack's 321, or the various variations thereof.

Jack's Hydro 5-12-26
Jack's Calcium Nitrate (it's just the brand I got when shopping for 321)
Epsom Salt
MKP
Magnesium Nitrate
Chelated Calcium Powder
and of course >1/4 TSP/Gal Fulvic/Humic/Kelp Blend <(organics)

The only problems I'm having is achieving elevated sulfur ranges and I suspect Jack's line of included micros is a bit lacking. I'm considering getting this >Micro Nutrient Pack< to achieve a slightly higher concentration of micros, but am doing more research to determine by how much I'll want.

don't forget your getting extra micros from your kelp, and the fulvic helps with micr nute uptake......

I spent a little time smashing some numbers looking to attempt a more concentrated solution. I'm now using a 1gram - 10ml ratio and that makes doing quick conversions stupid easy as I just need to move the decimal over 1 position, but then when multiplied by the number of gallons, the dose can get fairly large. So I divided ml/Gal by 10, 5, 2 and 1 and these are my results.

Making Concentrates ------ 3785.41 ml/Gal
1:10 ----------------------------- 378.54 grams (mild ratio for ease of accuracy)
1:5 ------------------------------- 757.08 grams (moderate ratio for larger systems)
1:2 ------------------------------- 1892.70 grams (liberal ratio)
1:1 ------------------------------- 3785.41 grams (the range most lines are mixed)

With the 1:10 mix, I add just under a pound of each component, but I fear if I try to make the 1:5 or greater, I will have a difficult time getting everything to dissolve. I designed and printed a squirrel cage mixing paddle and it works good with my drill, but I'm afraid to try and waste materials and was hoping others have mixed stronger strengths and can share their observations?
