Why is my PPM so high?!

  1. I’ve got two plants (first few days of veg) sitting in Fox Farms Happy Frog. The leaves look lime green and (I think) they feel good, not bloated or papery. I think they’re a little droopy.

    Today is only the third watering and the plants have never been fed. I checked the run off today and it measured 924. Is it the nutrients that come pre loaded into that soil making it so high?
    Someone suggested it about time I start to fertilize, but I’m afraid to do that now that I see such a high ppm
     
  2. Here it’s an hour after watering and tbh it looks worse. I had posted on here earlier this week and people said it was badly overwatered. Today the soil was dry down to at least an inch

  3. Happy frog has a lot of added nutrient in it . I never measured it before or any soil.
    I would just add my nutrients into water normally ignoring the soil reading .
    If you concerned do a 50 percent less veg nutrients as directions say until the plant gets about 12 to 14 inches tall then hit them with 100 % strength .
     
  4. sometimes the runoff reading is off because its all from the bottom for a true reading you have to run a gallon through her so i wqouldnt worry about ppms as as Whats the PH in and out?
     
  5. Ph in is 6.2, out is like 5.4
     
  6. That's pretty low, try bringing it up to 6.6-6.8 for a couple weeks and see if she gets better
     
  7. Crazy low! And I’m not sure why. I’m fairly certain that happy frog comes pretty acidic because I did a slurry test and it was 5 point something
     
  8. Use ph up and feed them at 6.6-6.8 for a few weeks and that should help
     
  9. Going to give that a try, thank you
     
  10. I did a gelato auto flower a while ago and had the same issue,ph was5.7, after a week of feeding at 6.8 she took off,I pulled a qp from her and then I switched to pro mix
     
  11. Test the pH of the water you give her, plain water,is it low
     
  12. What nutrients do you use
     
  13. The plant I'm talking about is my avatar picture
     
  14. That’s heartening news. I just read last night that it’s not recommended that you top autoflowers. Isn’t that going to lead to a much smaller yield?
     
  15. I have a starter pack from growth science nutrients but I haven’t fed the plant at all
     
  16. Well, until last night I had been using distilled water like a big dummy. Last night I used tap water that I lowered to around 6.2
     
  17. I don't top my auto flower plants
     
  18. Tap water is fine, but make sure you let it sit out over night
     
  19. Start feeding her at half strength, pH at 6.4
