This is an okay mixture, u need to re formulate and add a couple more key ingredient to make it a solid profile..
At these ratios u running a high nitrogen which is the reason why the flowers are looking a little airy.. But that's just my .02 cents...
Thanks for the info fresh starts. Thats a nice looking dry shot of herb. Is that the platinum og? I'm a few weeks into og ghost train haze, and I'm excited to see how it turns out. Then I'm doing a malawi diesel cross... I'll cut out the bloom booster next week when I change the res's. Are you flushing with EC .3 all the way till chop without any plain water?
I've been trying to find info on large scale greenhouse grows for tomatoes and such to see what those guys are doing. Anyone know if they use the same formula all the way from veg till harvest?
It depends on what you're interested in learning about but if you are interested in microbiology I would suggest reading "teaming with microbes"You have any other books you would suggest?
My goal is to be able to tailor my own custom hydroponic formulas for veg and bloom using raw elemental salt compounds- so yes I do believe it is necessary to play with profiles. My first few steps in that direction will be to emulate some of the prescribed fertilizer recipes made by plant biologists in that book I recommended.;) Right now I'm still observing my results with Jacks and understanding the chemistry behind it.So you don't feel it's necessary to play around with different profiles?
@Fresh Starts u are total correct I don't know anything about ionic chemistry or how to grow..You have not posted an optional nutrient profile to compare to Jacks and I highly doubt your understanding of ionic chemistry- you sound like a hydro store employee who thinks "adding a couple more key ingredients" will complete a profile. Don't just stroll into this thread and drop a two cents opinion that derails discussion with no factual information to back it up. Stop blowing smoke up my ass and GTFO :asshat::asshat::asshat::asshat:
@Fresh Starts u are total correct I don't know anything about ionic chemistry or how to grow..
What I was trying to convey is u will need another source of calcium in order to achieve a more well rounded formula as calcium nitrate has a lot of nitrogen when trying to achieve a higher calcium level...I actually formulated something for a buddy of my that has proven good results..
once ur ego gets over my comment about ur flowers try looking to reformulating and get more of a 1-1-3, 1-1-4,2-1-5 or even 2-1-4 formula.. Again this is just my .02cents and take it for what u will..
Don't were I won't bother derailing ur jacks hydro thread anymore ... Lol.. GTFO....
Im mixing my Jacks at 3g/G and my epsom at 1g/G and my cal/nit at 1.8g/G and MOST at .5g/G and my ph is at 4.7 why so low? By the time I finish adding ph up to my solution I have added another 140ml of potassium silicate. Is there a non potassium based ph up adjuster? Anyone have any idea where to get silicic acid powder?
I use the pH up Product from Nectar for the God's called, Olympus Up. It's Limestone and offers and additional source of Ca.Im mixing my Jacks at 3g/G and my epsom at 1g/G and my cal/nit at 1.8g/G and MOST at .5g/G and my ph is at 4.7 why so low?

NVM what I said about sulfuric acid surf I was thinking about down.I've been a little on edge lately and you're post came off as dismissive. If you have things to share with the community then drop the knowledge and ignore my hot headed post.
If you're PH is so low you are probably working with a water source low in alkalinity- which is good. I think the Ph up you are looking for is sulfuric acid. Potassium silicate adds too much K into the mix- and Jacks has a little too much K to begin with for use in coco. Thats why the magnesium is so important to use with the mix. (Thanks to Yo for pointing that out) Since I never have to use a PH up product (luckily) i'm curious to see this work out.
This is all the info I've got on the product so far, Ground limestone (natural calcite).My EC is at 2. with this combo. Is that Bad? What will that do to the plants? Its never been more then 1.5 and that was in flower. Im running the same mix for flower as veggie. Do you think the MOST could be responsible for the low PH? I just started using Jacks so im unfamiliar with it at this time and will be conducting several more experiments. Great find @GR33NL3AF Im going to try the limestone. I found a 25ld bag for 54 dollars. Is calcium carbonate the same as limestone?

It's already in liquid form... I believe the creator of this product feeds his microbes limestone and he bottles the bi-product. Which is enzymatic-ally digested limestone, making it readily available. In any case it works well, you will get VERY minor sediment but nothing that will clog or hinder your current lineup.Here is how it works Gentiles!
Adding protekt @ 3ml/Gallon or 150 ml
PPM-.20
EC-0
PH-7.9
Jacks @ 3 grams/Gallon or 150 grams
PPM-410
EC-1.4
PH-6.0
MOST @ .5 grams/Gallon or 25 grams
PPM-410
EC-1.4
PH-5.6
Magnesium sulfate @ 1. gram/Gallon or 50 grams
PPM-450
EC-1.4
PH-5.3
Calcium nitrate @ 1.8 grams/Gallon or 90 grams
PPM-650
EC-1.8
PH-5.3
Started with RO water 0 ppm. I had to add 50ml of protekt to final solution to PH to 5.8 bringing my final formula balance 113-41-204 or 3-1-5 + or - a few. Im going to start with 4ml of protekt instead of three this should get me to my proper PH without having to add more potassium silicate at the end of mixing. If I dont use the MOST my ph will be right at 5.7. Anyone not using MOST with Jacks in Coco with RO water? I keep my humidity around 60% in flower never had any issues.
Also on a side note @GR33NL3AF limestone is not water soluble how do you get it to break down and dissolve? I ordered the Olympus up from my hydro store but it wont be here for a few more days.
Couldn't you just add more water?Sweet. Good to know. If Im running 3 jacks and 1.8 cal/nit would my ratio stay the same if I lowered it to say 2 jacks and .8 cal/nit? Im trying to lower my ppm and EC its a little high for my comfort zone for veggies although Im not seeing any adverse effects from the high numbers. Damn I wish I had a room just to run all of my experiments.
Are you monitoring your runoff??? This is the most important, it will tell you if youre overfeeding...Im mixing in a 55 gallon rez. It would be easier to use less salt since the rez is already at max capacity. I cant add more water.
