Hi bert,

As you know i am not a great fan of cfl lighting, The lower leaves (anything below the screen) will do that due to lack of light. Saying that, there does look like something has taken a bite on the end if one of those leaves? The bottom photo looks like some water splashed on the leaf and burned it with the lights on.

You have ventured a bit out of my comfort zone with the LK, I have never used it so I can't comment on problems that may arise while using it but I doubt if this is the problem.

Dont panic, if the problem spreads above the screen then you may need to worry a bit but right now they don't look too bad. The hygrozyme breaks down dead root material and turns it into food, I doubt this would be a problem either.


Hope this puts your mind at ease
