yellowing orange tips

one of my leafs that ive been having problems with just a couple hours ago started to turn orange yellowish at only one tip.

its bearly at the tip any one know what it can be i trimmed the little tip of to hopefully stop spreading but if it starts again does anyone know what it can be????

I used to do that, cut the sick part ! But it doesn't solve anything ! Maybe if you post more pix people will tell you what the problem is ! 80% sure not burns ! Burns don't turn yellow ! Brown from the start !!

alright mate well i need a better camera with better resolution because my camera is garbage so i will try to put that together for you guys thank you. And so far the coloring has not returned so i hope it help not spread but your the more experienced grower so weyl see what happens if it returns and il put more pics thank you lad

This picture has good resolution ! I just need clear parts of the plant!

well its hard to see but the discoloration you can bearly see at the left part of the tip on the middle leaf its very small but i wanted to get to the problem before it spread
