Masterblend 3 Part Feeding Chart?

Discussion in 'Nutrients and Fertilizers' started by Shawnery, Feb 26, 2018.

  1. Just wondering if anyone has any experience with MasterBlend in a hydroponic system? I'll be running s 3 part "system", not really a system, fert 4-18-38 / calcium nitrate 15.5-0-0 / epsom salt.

    Any experience with ratios and charts out there is appreciate some advice.
  2. Those last numbers are just crazy
  3. It ends up being 20-18-38 when used together.
  4. Just a note to point out that when you mix the masterblend, calcinit and epsom together as a dry mix, the final N-P2O5-K2O grade is not 20-18-38.

    It is more like 7.8% nitrogen, 7.2% P2O5 and 15.2% K2O.

    1.6 units of 4-18-38 = 6.4 - 28.8 - 60.8
    1.6 units of 15.5-0-0= 24.8 - 0 - 0
    0.8 units of 0-0-0 = 0 - 0 - 0
    sum them= 31.2-28.8-60.8
    divide each by the total number of units(4)

    yields a final mixture with 7.8% N - 7.2% P2O5 - 15.2% K2O

  5. Any idea on ratios and ppm numbers? I've been reading about it and been seeing large number around 2.0EC and higher. I assume that's off by a bit but who knows when you switch around.
  6. I found this but you can find anything online.

    12gms fert, 12gms cal nit, 6gms epsom per 5 gallons.

    1200ppm seedling
    1500ppm vegetation
    1700ppm flower

    Seems a bit high?
  7. Changed out the solution and decided to try the Masterblend, Calcium Nitrate and Epsom Salt. Has a nice clear Sprite bottle color to it when mixed with water and no smell at all.

    I ended up using,
    12grams Masterblend,
    12grams Calcium Nitrate,
    6grams Epsom Salt,
    per 5 gallons,
    ended with 600ppm or 1.2ec.

    Just thought I'd update the numbers since my numbers ended up being wrong last post.

  8. I used masterblend at beginning of r flower at 1000ppm and it burn the shit out of my girls.
  9. I'm using Masterblend @ 2.2ec, veg, and it continues dropping and the plants are growing like hot cakes.

    I wonder why?

  10. Just completed several girls using masterblend. It was a nervous few months but over all turned out well. Some plants did receive the tomato mix of this set of nutes in the beginning. That seemed a bit heavy though most strains tolerated it. It seems each strain liked something different. For instance SLH doesn't like anything over a 20-25% mix of masterblend. RQS Critical suffered unless we kept it near a 65% mix. During Flower I've run 75% of masterblend recommended nutes, [totally ignored the recommendation and gave the same amount of ep salt], Cut cal-nit down to 55% of the recommended mix. Both RQS Critical and Amnesia Haze loved this. 8 ball is doing ok with it but it has a ways to go before the verdict is in on 8 Ball. We'll be throwing in some Blue Dream and Pineapple Express. I am relatively new at growing my own medicine so if anyone has recommendations or critique it would be appreciated.
  11. I'm growing Gelato this go and I started at 12g mix/12g calnit/6g Epsom and gets you around 1.2ec. I started at 1.2 for my 5 inch clones and went up relatively quickly through my nearly 2 months to a total of 2.2ec.

    With this setup my girls do very well and lower the EC by .1 per day. At the same time my ph rises by .1 per day and my 8 girls drink above 5 gallons per day. With my limited experience that's a pretty perfect readout of variables in hydro.
