    Hi, don't take my word for it but it sounds very similar to what I just had on one of mine. It was diagnosed as calcium deficiency caused by a lockout due to me overfeeding. Check out my thread in the infirmary section:

    A good flush later and I think its been sorted.

    hi mate... yeah looks different to mine, seems to be mostly on the tips of your leaves, I did read somewhere the tips are first place to show an early indication of nute burn, but I really have no experience so don't take my word for it!

    If I were you I'd put a post up in the "infirmary" section, I'm sure someone with more knowledge than me will be able to help you out.

    Good luck!
