Brown spots on leaves

  1. Hey I have a seedling about 3-4 inches tall. It's growing everyday but I've noticed the lower leaves have started to develop brown spots. Does this mean they're dying? How can I fix this?

    90W LED 7:1:1 Red Blue Yellow
    Moon Dust Fertilizer
     
  2. Hey Tony, without pics I am throwing a frisbee in the dark here but if you are starting with a decent soil, your babies should not need the moon dust nutes yet. I would do PH correct water only for now and make sure they have a little dry time between waterngs to get some oxygen to the roots. Once they are 30 days old or so, you can start adding some diluted nutes and gradually increase to the recommended dosage.
     
  3. Actually I'm using hydroponics. I thought I posted this in that category. So ur saying I should use any nutes yet and just use plain water?
     
  4. Hey Tony, with hydro I recommend water only or really diluted nutes (1/4 strength) or weaker till your grow is a month old or so,
     
  5. pics or it never happen
