    Are these nute mixes specific to working in coco, or is it ok for soil as well?

  2. xDBxMitchxDBx420 on May 16, 2022 at 4:13 pm

    this videos just told me wht i do with my nutrients (im doing what ur vid says)and i was just told in a comment on my video im doing it wrong….. lol 😂

    So when it’s time to feed the plants, how much of the X ppm prepared solution do you pour into the plants, a few drops or saturate plants with the solution?

  4. Evan Schneider on May 16, 2022 at 4:14 pm

    I suggest you dilute your ph down solution before adding it

  5. Ears that Hear on May 16, 2022 at 4:16 pm

    Thank you for this vid!

  6. Irv Pena on May 16, 2022 at 4:18 pm

    I’m pretty sure ph buffers(GH PH down) change the EC🤔

  7. Heyron 420 on May 16, 2022 at 4:19 pm

    This is what i was looking for. Thanks dude.

  8. TOPSHELFBOOG on May 16, 2022 at 4:19 pm

    I love how detailed and specific you are

  9. Scott Little on May 16, 2022 at 4:21 pm

    Where would floralicious plus fall in this list

  10. Dan Forr on May 16, 2022 at 4:23 pm

    Dudes not joking about the ph balance… Fucked my whole day up

  11. losFondos on May 16, 2022 at 4:23 pm

    What dosage rate do you use for CalMag? How much of the total EC should come from CalMag?

  12. Scott Little on May 16, 2022 at 4:25 pm

    Ahhh I see. Floralicious would fall in after bloom. Great video. Stealing the velcro syringe to the bottle idea.

  13. Kean Salzer on May 16, 2022 at 4:27 pm

    Now that they have stopped making SM-90 what do you use?

  14. Saintist IST on May 16, 2022 at 4:28 pm

    Hi Doc , 10x for the great content! Q: would it be possible to have 2 Nuts schedules? 1 as per your video and the other Nuts from plant origin, like this product says: All fertilizer ingredients contained in this product are of plant origin, Aloe Vera (Barbadensis Miller) Extract, Seaweed (Eucheumoid spp.) and Molasses.100%. vegan.
    Just like breakfast is not the same as dinner. I wonder if the 2 diff. types would conflict with each other although fed at different times of the day.

  15. Tyler Rockey on May 16, 2022 at 4:30 pm

    Can you use this for soil??

  16. Igor Zh on May 16, 2022 at 4:32 pm

    Thanks a lot, Dr MJ Coco!
    Please tell me how long a ready-made solution can be stored in a bottle? Solution storage time.

  17. sammy knows on May 16, 2022 at 4:33 pm

    how about mixing your own with the 6 pack

  18. Ajay Matla on May 16, 2022 at 4:34 pm


  19. James Cipriani on May 16, 2022 at 4:40 pm

    Step 1) Start With Silica. Related Products. .
    Step 2) Add your base nutrients.
    Step 3) Add your cal-mag.
    Step 4) Add any other additives last.
    Step 5) Finishing by pHing your nutrient solution.
    I have always used this order. You have steps 2 and 3 switched. I have never experienced lock-out though. I am just curious to if cal-mag sequence matters at all then? LOL

  20. BLS 18 on May 16, 2022 at 4:41 pm

    For what period would this feeding be ? Veg or flower ?

  21. Amith Malik on May 16, 2022 at 4:42 pm

    My nutrient mix is always clear

  22. Betsy Guerrero on May 16, 2022 at 4:43 pm

    Quick question dr coco .. when using the ppm /ec meter should I be reading the ppm ? Or the um/cm reading ?? Thanks

  23. yvon pilon on May 16, 2022 at 4:44 pm

    where’s your feed charts , cant seem to find them on your site

  24. Zayron Zayron on May 16, 2022 at 4:45 pm

    For big bud plant how much?

  25. Amar Ramdial on May 16, 2022 at 4:46 pm


  26. Kin_Kola on May 16, 2022 at 4:46 pm

    I’m a new grower, should be getting my first seeds in the mail today… Can’t wait!! Anyway, I just wanted to say thank you so much for this video. I’ve been watching videos for the last 3 weeks and I’ve been so confused on how to feed, but this video made it very clear and understandable. The other videos are using a different medium or different nutes, etc.. you’re using the same things I purchased so this is exactly what I needed to see right now. Thank you, thank you, thank you!!!

  27. Jhon Wayne on May 16, 2022 at 4:47 pm

    My question, what feeding schedule are you going by?

    I can’t find the feed chart on the site. Please help.

  28. J T on May 16, 2022 at 4:47 pm

    You say “cay-shun” in all your videos when discussing ‘cation’. Please use the correct pronunciation “cat-eye-on”. I’m a chemist, and I’m here to help.

  29. paperclip on May 16, 2022 at 4:47 pm

    Im a noob grower, but Ive managed to set up a very nice dwc grow. Ive noticed that there are different information on how to add nutrients, additives and supplements in the correct order. Does this apply to dwc as well? btw, this is the best information ive come across. Thx for the tip on bloom booster and humic acic..subbed

  30. AL S on May 16, 2022 at 4:47 pm

    Just started using GH. Made a test batch and noticed the EC shot up after adding nutes. Had to empty almost 2 thirds just adding fresh water. Is that normal? I was using tap water?

  31. Richard Robinson on May 16, 2022 at 4:52 pm

    Phototron nutrients charts

  32. Dama BJJ FLoraMax on May 16, 2022 at 4:53 pm

    Can i do silica before put water in fridge to reduce water temp ? usually i do 1 hour in freezer to reach 19c

  33. павел козырев on May 16, 2022 at 4:53 pm

    How long does that amount usually lasts,until you need to change it

  34. Rosie B. on May 16, 2022 at 4:53 pm

    Looking at the Nutrient Schedule I was wondering what amount of the Dry Koolbloom I should be using during the "Ripen" week.

  35. Zach Gallese on May 16, 2022 at 4:55 pm

    As always you’re blowing my mind.

  36. Jesse Stewart on May 16, 2022 at 4:58 pm

    Do you have a video of Ph runoff drifting up with coco?

  37. Thomas"cannabisconnoiesaur" Cooper on May 16, 2022 at 5:02 pm


  38. X.3 on May 16, 2022 at 5:02 pm

    My main takeaway was that the ratio between calmag and EC is important for nutrients absorption

  39. g metz on May 16, 2022 at 5:02 pm

    You mean your ppm is 1100?

  40. djSpinege on May 16, 2022 at 5:02 pm

    I’m wondering if your plants needed more water than say 4L would you mix up a larger batch of nutrients or is it ok to water with plain water after feeding?

  41. Scott Streeter on May 16, 2022 at 5:05 pm

    I have a question for ya .? What do you do with your leftover sullution. I’m still using 5 Solo cups for my first containers. And why does the ph goes up while it’s stored. I feed mine about twice per day. On the second feeding I test my ph and it will be higher than the first feeding. And or in another video about your nuts can you tell us what to do with the remains leftover sullution. Do you have to mix new every time?? Mix one gallon for one solo cup? Thank you I am a big fan I have your grow guide . You have help me threw 4 grows now . Thank you Dr.

  42. Whatzupjay Channel on May 16, 2022 at 5:05 pm

    How long for this formula?

  43. Mohammed Bathia on May 16, 2022 at 5:05 pm

    Very informative! Love the website. How do I know if I should use hard water or softwater nutrients? I use borehole water with a ppm of 90

  44. Rusty James on May 16, 2022 at 5:07 pm

    Can you use organic dry amendment, top dressing ,, fertilizer?

  45. Sean Wright on May 16, 2022 at 5:07 pm

    What happened to this Series this was a great reference guide for coco growers

  46. Buns 57 on May 16, 2022 at 5:07 pm

    Your website taught me everything i know i dont know where my plants would be without you i am a new grower in VA. in week 5 of flower growing ice cream cake looking frostyy

  47. SaGe Ninja on May 16, 2022 at 5:08 pm

    Ewwww, Synthetic bottled nutrients..

    I’ll stick with my organic compost teas.

  48. HempWithGG on May 16, 2022 at 5:08 pm

    Where has the gem been hiding .? Awesome video. Growers love

  49. Reviews By Steve on May 16, 2022 at 5:09 pm

    Hello thanks for your video is in EC of 1200 the same thing as a ppm of 1200? and is that a good PPM for young seedlings? thank you

  50. Psyience on May 16, 2022 at 5:09 pm

    Saved this for layer. I ordered whatever i didnt have, nectar, cal-mag, wetting agent etc. Do you give the ratios anywhere?
