I posted these close ups Because I thought some one might know what category disorder it is at the least?

My nutriment regime varied at the beggining but now am on ot1s biobizz guide 2nd week flowering so i dont think feeding has been the problem

looks like rust spots , think you got a fungal infection

Soz I couldnt get better pics up but ill get something for fungal infections and see what happens it hasnt spread to any of my other plants and its been along side them along time but as i got some more plants (If they germinate) on the way want to root out all problems! nice one !

or pottasium (K) deficiency

Could be some nute burn or lockout as all the tips are brown.

Rusts and other such fungals dont normally affect the tips so much but is seen on the actual leaf, usually mid vein or along the veins.

Like Scraglor said, it could be Potassium (K) deficiency, which could be caused by low temps, too much magnesium, e.g Epsom Salts (causes K uptake to decrease or lockout)

What medium are they in?

Westlands+ with added ji started with miracle grow witch was burning them horrid! The pic of the full leaf was an old one the tips are back to normal now the rust colour starts on the edges and goes inward ill post a fresher pic if i borrow a better camera!

Found this link in knowledge base looks like my problem was mg deficiency Inter venial Chlorosis http://www.uk420.com/boards/index.php?auto...ownloadfile=395
Fed all my plants on Saturday with some epsom salts added and the problem appears to be clearing up ! once yellow rusting leaves are now appearing lush green! Ill post back after a week and let you all know if this has solved it!

The problem is not happening anymore but now on rainy days I pluck the buds off that plant so theres not much of the plant left but it definately solved the problem!

Prob came back not to worried as this is only on the one plant still and this plant is going soon! Got a better pic than before so I thought id post it would still love to know what it is? wouldn't be surprised if it is fungal after all!
