  1. go ec. thats universal. they say 'ppm' and thats US and thats a 500 scale. they are talking abour TDS and NOT PPM. thats on a 700 scale. so 1.0 ec = 500ppm = 700 tds. don't confuse them they are not the same. they are talking tds in the vid. surprised the guru guy didn't straighten that out. use a 1.2 ec.

  2. Dudes, my last grow I got great results Gaia green top feed. Straight water from the tap oxygenated. No problems never measured ppms. Just my water it was 200. Ppm my results were 🔥. Not sure how high Gaia green brings up the ppms but my plants loved just tap water oxygenated.

  3. That was awesome Dude, helping out a newbie with the free Remo kit, I been using that kit for a few years now and its amazing product, I never grow without using Recharge.

  4. I like to hit the ladies with a stressful 1400ppm dose of straight K around day 46 with 65 day strains. This gives an obvious flavor & aroma boost and also works on tomatoes to increase lycopene. For regular feedings I hit them with 250 to 1100 ppm depending on plant volume keeping osmotic pressure in mind.

  5. Here’s a question ?! I’m new to dwc and was hitting it out of the park until I made a simple mistake and my ph was too low it flipped my autoflower but I didn’t notice it had a problem for about a week little less but it got me to wondering if it stunted in flower would this count as time flowering obviously it won’t matter it’s when the terps look done but does it stop it from finishing if it’s Stunted ?! Just about to become a Memeber and get some recharge I appreciate the help

  6. i have not been able to find an answer to this question. PPM meters are 0.5 or 0.7 settings, but GH and most other the Dutch master that I've found do no specify what setting to use. I was told 0.5 and Dutch are also 0.5 but you said 0.7 so what should i use.

  7. Early veg = 600-800ppm
    Aggressive veg = 800-1000 ppm
    Transition period to flowering = 1000 ppm
    Flowering = 1000-1200ppm
    Last 2 feeds of flowering =1200+ ppm
    Last 10 days of flowering = flush with PH balanced water.

    These are just guidelines that has worked for myself from the past to present. Some strains I have grown is lower some are higher. These are the baseline measurements and I adjust to the pants needs, size and stage of growth. The plants will talk you….just listen.
