rep to anyone who gives the advice to fix this problem

so i came home today to see my plant bigger but it has like yellow on the middle of the leaf but no wheres else...what should i do? other then the yellow its fine...and oh ya, the yellow isnt dry it's just as moist as the rest fo the leaf...thansk for the help.cheers

Pic would be nice

Could be a lot of things

Could be a nute problem....

How old is your plant?
How many internodes?

how close is the plant to your light and what kind of light are you using? A friend had a 400 watt HPS and it was a little to close to the plant and it bleached the leaves yellow/almost white so think about that

here is a pic of the bleaching, the second pic is what happened when he didnt move one of the plants, but the other plant is fine now.

thanks mvg...i posted this and went to my plants its turns out my 13 watt flo got hott for soem reason...i put my t-12 backon...im sure its the bleach problem...ook pretty near the same prob...thansk and i gave ya rep

yeaaaaa just dont let what happened to the second plant happen to your plant unless your into that crack stuff then go ahead and keep it real
