    Help diagnose a problem

    Can anyone tell me what's going on here?

    Pretty standard setup. Growing in soil, LED lights, RH around 50-60%, temps around 75F
    24 hours light, good ventilation, growing in potting soil, nothing fancy


    It's like they were green and healthy one day, and literally the next they all looked yellowed and brown spots all over. I have grown three successful crops in this setup, with no problems whatsoever. The fourth attempt they barely made it three weeks and they all just got dried out and turned into husks in a few days. Now this. It's like I can't grow a single seed to save my life.


    PS: Just put the brown, spotty leaf under the microscope and I see no evidence at all of any kind of infestation. No eggs, no bugs, no remnants, nothing

    I see PH issues, but are you saying the soil has been used before? IF it was used before what did you do to revive it? Are you feeding anything? The soil may be out of grow power.

      This is almost all new soil. The conditions I have been growing in have been successful. After the third grow I decided the soil needed to be changed. I added a bit of blood meal, but that's pretty much it. Scott's potting soil is basically all it is. I have fed a couple of times with Miracle Grow all purpose, always following the instructions so I don't go overboard.

      I'll go do a PH test on the water I am using. It's tap water, but I am letting it sit in a bucket for at least two days before using it to dechlorinate

    Tap water will vary, and many have switched to chloramine and no longer use chlorine. Chloramine does not gas off, contact the water co and ask what they use.

      I just found out as of 2019 my city is treating with Chlorine. I don't believe it has changed but I am looking into it. Thanks for the tip

      Have not had any problems with it before. Which isn't to say I swear by it or that it's a great choice over others. Just never seemed to have had any issues with it
