potassium problem?

  1. High all.... check out my plants and let me know what you think.

    From the reading I've done, it seems lilke I have a pottasium(K) problem with my plants. Don't know what to say about the runt, they were all planted at the same time.

    Does it look like a pottasium problem?

    Growing under 400W MH light for almost 4 weeks now.
    No nutes
    watered with tap water (let it sit at least 24 hrs. before I use it.
    temp in room anywhere from 71/84F depending on time of day/night.
    forgot what type soil, but there are no nutes in the soil... I have added perlite and also some "soil moist" granules that help retain water.
    I've got 3 fans in the closet to try and help with moving the heat out.
    don't know the ph level either

    thinking about adding some nutes

  2. hello hello hello
    is anybody out there?
     
  3. it doesnt' look like a nutrient deficiency to me. I've had a few leaves on my clones with dried spots like that but it didn't hurt the growth.

    If you'll feel better, add a balanced fertilizer. like chicken soup, it can't hurt (unless you go crazy with it.)
     
  4. thanks for the reply, going out of town for the week. I'll see what they look like when I get back. I might add some nutes then... I wanted to try and do this grow without any.

    We'll see, thanks again
     
  5. Potassium, don't think so. Judging by the slight heat stress I am thinking that's what it is.
