  • Hi there Skybound

    I read your threads pretty closely a few months ago as I wanted to prepare my own nutrient solutions but ultimately decided to go with straight MEGA CROP based on your recommendation. But now that they have released an A + B formula I've regained interested and plan on doing what you did with using Jack's 321 as your base.

    I was hoping I could pick your brain on that subject, would you mind starting a conversation with me? i don't think I'm able to with my new account - I keep getting an error.

    *Just saw your comment "When mixing, I add the silica first, micros second and calcium last"

    Is this the order that you still use?

    Calcium is known to easily bond with P and S and become colloidal and I believe this is why it's preferred to be added first, or 2nd if adding silica. I can't quite remember why the Si must be added first, but I suspect it has to do with stabilizing the PH, where if it were added last, the PH readings wouldn't be stable or accurately read. Back to calcium though, it's the most difficult element to uptake because of the many things that can take it out of solubility, that by adding it to the final solution first would give it the best chance to remaining in suspension and not precipitate out. FWIW, I add my stuff Silica, Micros then CalNite.

    You have a nice and complete lineup to start out with. I also regularly use ammonium phosphate, just in super small quantities, but Megacrop's standard of setting 5% of their N to be ammonium and the other 95% nitrate which for cannabis, I find to be about ideal, so I adopted that little bit of knowledge into my feed programs.

    Also, I've read that calcium flows through the plant by hitching a ride with nitrate, so don't thin out your N too much as doing so will hinder your Ca uptake and make the branches weak.

    Another convenience of mixing the salts into a concentrate is because once they're wet, you don't have to worry about that portion of salt gaining weight by absorbing atmospheric RH which will then cheat your scale readings. Micro mixes made from sulfates must not be made into a concentrate, but all of your complexes can and IMO should. I mix 1/2 gallon of each at a time and add 1 gram of salt to every 10ml of water in the jug, so when using hydro buddy, I can easily and quickly shift the decimal over one place and interpret that as how many ml is needed to achieve the dose. This then saves me from having to weigh out each salt complex each time, I just take XX ml of this, XX ml of that and XX of the other etc, and it makes mixing up nutes very quick and accurate.

    I've never grasped the value of making AB mixes, so I never learned, I just mix my salts into concentrates and reserve the liberty of changing any macro or secondary element to my heart's content and since I began mixing my own, I tried about a dozen different feeding regimens, plus 3 more that I use for making plant food for garden veggies as all of those plants have different preferences too.

    Thanks for the insight and I like your point RH absorption

    Much appreciated

    What's going on my skyboundhighbound homie!!! What you growing lately ? You doing good???
    I was wondering if you ever got your nutrient ppms in order. I just read 14 pages on your thread and I'm literally going threw the exact same train of thought you did. I just almost ordered MOST from Jack's. I stumbled across your thread. Any findings you found or tweaks in your recipes ppms I'd love to hear about. It would definitely save me alot of time.

    I spent a LOT of time in chapter 5 learning how the elements express deficiency/toxicity, plus also how they compete etc.
    Hello Sky, hope you don't mind me messaging you. I am just starting Cap'n style and would really appreciate some advice, just basic stuff.
    I have an 8 pot recirculating system 200 litres (an old rdwc system I have converted). What kind of ec levels would you feed in this system. I use GH 3 part, silica, cal/mag and a root stimulant early on. Final pot size is 20 litres with clay in the bottom then the rockwool cubes. Feeding 2 x per day for 20 minutes.

    I did try this my last grow but the roots grew out of the bottom and into the solution, so it was a hybrid and didn't work out so well, probably due to under feeding @ 1.1 ec excluding 0.2 background. I will probably go sterile rather than live, just find it easier and have had rot with beneficials.
    Any advice at all would be much appreciated.

    If you're going sterile, you might as well start by not holding yourself to what is or isn't Capn style because I shit you not, step one is using beneficial bacteria, lol. I have no problem with sterile, but it's my experience and study that more root problems can come from sterile than live, but this doesn't imply that live is fool proof.

    Irregardless of the medium, I highly recommend ditching the GH and order Megacrop. It's a dry nutrient that's formulated for cannabis. If you reach out to them, they will send you a half kilo sample if you pay for shipping. You can use up your silica and calmag with the megacrop too, but after I ditched GH years back, I began making my own nutes from salts (link in signature) and now am growing my very last Capn style plant in bloom and am switching to soil.

    That aside though, if you're doing your version of Capn style, then I assume you've done plenty of reading so why waste time rewring what he alrerady wrote and you already read? So if you have a question, I'll do my best to answer.
