Help, please! Nutrition problem?

[Mrgrow]

Hi! I seem to have a problem with my flower.. Cause the tips on the leaves are turning red/yellow/grey.. Dunno what to call it! And my camera is broken, so I have problems uploading a picture of it =/

But do anyone know what this is caused of? Would like to correct the mistake so the flower can become happy again!

Thanks in advance.
MrGrow :)

Woefully little information, too little for anyone to hazard anything more than an educated bunch of guesses.

There is some info about my soil and nutrition that I use for now ( will upgrade to canna coco soil and canna fertilizers later on)
I know my lights are somewhat amateur for the plants, pretty sure of it... But should that be enough to yellow/redish the leaves?
I was thinking nitro~ was to low.. But hey! New to this. So appreciate the help I can get.

Colors as you're describing sound like late-season (autumnal) changes, which do naturally occur in many strains of cannabis. No way to get a photo or something that would allow us to better see what you're describing?

I have to be honest here--I have yet to figure out exactly what causes that every time. It could be fungus gnats, it could be overwatering, it could be scorch, it could be some other pest, or it could be an injury.
