Possible nutrient problem.

Discussion in 'Growing Marijuana Outdoors' started by Satuit020, Jul 11, 2019.

  1. Out of my 12 plants I have 2 that are showing this on their leaves. Not sure if it could be a nutrient problem or maybe too much nutrients. These plants are growing In 10 gallon containers in fox farm soil. I’m giving them big bloom and grow big about 3 times a week at half strength. Any input is greatly appreciated.

  2. See any bugs? If not I think it looks like ph fluctuation. Growweedeasy.com has a great section that I match pictures with.
  3. I haven’t seen any bugs on the plants. They are currently in a greenhouse and I leave the door and vents open during the day for the heat. It’s weird that only 2 of the 12 have these problems. Maybe the others will show the same soon

    Or possibly leaf septoria but these are just guesses based off co.parison to the pics

  5. thats looks like it. I have been just using the tap water to water the plants. I guess I will have to start checking the pH before I water. Thanks for the help.

  6. It looks like it's only on the older leaves, the newer ones I see look okay. If that's right then maybe you had a problem but now you don't.
