    Anyone here use Cyco Nutrients? Looks like you can buy 20 liters for around $90 delivered off of amazon (just a hair cheaper than GH) and Cyco is a 2 part system. Running the numbers looks like 7ml equally of part a and b would only require a very small supplement (under 1ml and under 1 gram) of CalMag and Epsom respectively. Right now I'm using slightly more ml/gal than that of GH's 3 part system so it's a small cost differance plus you use just "slightly" less product and both grow and bloom a+b are 1:1 ratio's. I think it would be worth the switch... The labels only list the n/p/k/mg/ca so I am waiting for an email back of all of the micro's along with percentages...

    don't need both unless you want a ton of Mg.

    if you want to stick with GH, use Lucas formula and you won't need grow, just micro and bloom.

    I'm using gh floranova bloom only ,tap water & 3 ml. calmag works good it's a lot less work than the 3- part flora series I'm using in another grow as well I'm reading more &more journals using cyco nutes all the time

    CalMag doesn't supply that much Mg... For every 1ml/gal of CalMag you end up with 4ppm Mg and 13ppm Ca. Epsom at 1gram/gal adds 26ppm Mg (along with some sulfur). That's why sometimes you need to use both. The Lucas formula is an easy formula to use for sure, and I used it when I first started out, the drawback of Lucas is that it is not the most ideal formula.

    i had trouble measuring out the floranova. and alot at the bottom of my res.

    have you tried the duo yet? i liked it. was trying dyna gro but i'm going back next run. part A and B for veg or bloom

    if you need to add cal/mg and epsom, you need a different nute line.

    i've gone away from Lucas and keep coming back.

    keep us posted on the cyco. never heard of them but nutes are nutes in my opinion. the NPK is what's important as some are better for cannabis than others.

    Yes nutes are nutes for the most part I couldn't agree more, I am looking at them (Cyco) as being a little easier to use and a little less $. NPK is as important for sure but there is also a relation between K-Mg-Ca that if not kept in the right ratio or at least close to it will cause lockout which most people mistake for a deficiency. What base nutrients do you know of that have a sufficient amount of Ca and Mg?

    dyna gro foliage pro. and GH flora duo. haven't had to use cal mag in awhile. even with RO water.

    The GH floraduo doesn't look bad, actually looks pretty damn good The dyna grow however...

    Feeding at 5ml/gal
    N 129ppm
    P 17ppm
    K 66ppm
    Ca 26ppm
    Mg 7ppm

    Nitrogen looks good but everything else is wacky... you've used the dynagrow with nothing else? I'm surprised you didn't have problems if so...

    had been using DG FP for veg and then switch to Lucas for bloom. this grow used DG all the way thru and was not impressed in bloom. hence my earlier statement about always keep coming back to Lucas.

    the flora duo has worked really well in bloom as the Lucas formula. it was decent in veg but i give the edge to DG for veg nutes.

    the DG would need to mixed with DG bloom or grow or a combo of both to get a proper bloom profile in my opinion. i'm just going back to tried and true Lucas.

    what npkmg is your goal? i go for 100 for N and P and 200 for K and 60 Mg (all ppms)

    This is where I am at right now with my veg and bloom formula..

    Veg:
    116 N
    23 P
    132 K
    41 Mg
    83 Ca

    Bloom:
    N92
    P41
    K138
    36 Mg
    73 Ca

    The P ends up being higher with PH adjustments

    pop this in to the computer, i'm curious if i calculated correctly:

    5mL floraduo a and 17mL floraduo b should come out dead nuts on lucas target

    @rkymtnman
    N 111
    P 98
    K 215
    Mg 40
    Ca 67
    The K seems a little high and the Ca a little low. There is a relationship between K-Mg-Ca that should be between 3:1:2 to 4:1:2, the relationship between Mg and Ca should always be as close as possible to 1:2

    The Lucas at full strength is:

    N 106
    P 92
    K 193
    Mg 63
    Ca 105

    A little low in N for veg I would think, looks like it would work ok for flowering although a little high in Mg.

    I like this a little better, should do good in flowering and the balance between K-Mg-Ca looks good. 8ml micro and 14ml Bloom (as opposed to 16ml)

    N 106
    P 81
    K 171
    Mg 55
    Ca 105

    I always though the NPK formula ratio was 3:1:2 during veg and 1:1:2 during flower. At the moment I'm using that and things are going well but I only hit them full strength once the plants are about 10-14 days into veg and then into flower

    I run the Cyco base nutrients, no need for extra cal-mag even running RO.
    This is my whole line-up for veg.
    DSCN0737.JPG
    And this for flower
    DSCN0738.JPG
    At 5 ml each per gallon, gives me around 450 ppm (.5 conversion). And I get these from said mix and strength. DSCN0675.JPG DSCN0629.JPG

    where did you get this info from? and this is specifically for cannabis? if so, i need to tweak my Duo recipe a bit. maybe just use 1/2 well water which should bump my Mg and Ca up in my situation.

    I got this info from @im4satori. He's helped me out quite a lot with understanding nutrient profiles and correct feeding ratios. I'm not sure I would want to use well water for extra Mg and Ca unless I knew how much extra I was was actually giving, I guess you could always have it tested, I am pretty sure that when you have your water tested they tell you the PPM of everything that is in your water.
