ergh..

whats the PH levels?
have you checked thoroughly for insects (including under leaves?)

i'm no pro but it looks like some sort of mould to me!

you growing in soil? try and keep the ph at 6.5 or just above. i use potassium hydroxide at little amounts: e.g. i fill up a 3L coke bottle with water for my feed, and check the ph before adjusting it.. i use a 1ML syringe and measure out 0.1ML at a time and keep checking the PH so i know for future how many ml to add to the 3L of feed!

^ just incase you didnt already know lol.

i would be careful that it isnt mould though, it looks grey to me.. and i dont know of any plant problem off the top of my head other than mould/mildew. if anyone more experienced comes on this thread then im sure they can add their thought on it!
