Brown Leaf Not Sure Whats Causing It. Nitrogen Deficiency?

Discussion in 'Sick Plants and Problems' started by Ciarán69, May 31, 2019.

  1. So I have searched online but I cant be sure whats causing it. I have a lower leaf & a leaf at the top of the plant turning brown.
    Im growing with Biobizz soil & nutes.

    Any help is really appreciated

  2. Try looking up fungus gnats and see if those symptoms are similar to what your plant leaves have. Just a suggestion.

  3. Thanks for taking the time to reply, I appreciate it!
    I cant see anything on her & I check her regularly.
  4. Is the bottom leaf browning or paling/yellowing and is it just one leaf or several? If the bottom leaf is an even paling/yellowing of the leaf, then perhaps it may be nitrogen deficiency.
  5. Thanks for taking the time to reply
    Its a leaf at the bottom & a leaf at the top. The first pic is the top leaf the second is the bottom.
  6. Yea that's a tough call. I can't think of anything else. Has it spread throughout the other leaves yet or still just those two leaves? You don't think by some chance the bottom leaf simply was just laying on the soil and the hot soil just did that to it and the top leaf perhaps some nute solution drops fell on it? How's about a pic of the whole plant? Maybe there's something else I'm missing.
  7. Thanks for your reply!

    Here is a picture taken at the same time as the two above. I was thinking that the nutes in the soil burned it & I also gave all of her a foliar spray of Acti Vera from Biobizz. But I'd expect it to show up on a lot more leaves if its nute burn from the spray?
  8. Pics not showing lol. I personally never foliar spray my plants with anything except small mists of water when they're baby seedlings. After that, I let the soil or nute do their thing. However, I'm not too sure that would've caused this to happen. Otherwise more leaves would be affected like that. Weird.
  9. Biobizz recommend using it to help protect against mould etc... I had some PM earlier in the grow. Im an idiot! I forgot to add the picture. Here it is...
  10. I see several more leaves with holes on them. Were those leaves like that from the beginning? Did you also look on the underside of those leaves for possible pests/bugs?
  11. Yes I have been looking regularly. A few of them are the way they grew & I'm assuming one or two are from me handling it, tying it down etc...
  12. Only thing I can suggest is to just wait it out and hope it doesn't spread to the rest of the leaves. Let's see how she looks a week from now.
