Maybe PH?

OK so I was looking at my plants today and I noticed that both of my plants have some yellow spots on the fan leaves. Now its just on one of the fan leaves on both plants so I am just wondering if it is getting that time to trim them. I was also looking in the Chart and it kinda looks like it is a PH problem but being that it is on both plants and only one fan leave from both it is kinda hard to figure out.

Any Ideas?

need pics.....

here ya go

im sort of having that same problem too, im using the bubbleponics grow for my first time and i heard that ph can kill the plants quickly too if its really out

look into light bleaching

I would think that he hole plant would be affected not just one fan leave. But Im really not sure.

Wouldnt light bleaching affect the whole plant?

and if it is light bleaching is the problem would raising the light solve that?

light bleaching doesnt necessairy affect the entire plant-there could be some hot spots. what type of lights you using and how far away?

it is a 25 watt m/h and it is about 6" from tops

it's possible with MH. if there are too much nutes, than the lower fan leaves would the be the first to experience light bleaching. nute burn is caused by excessive evaporation of water in the leaf leaving the nutrients that will burn with significant light intensity.

what ph are you running?

Well this is my first grow so i am piecing together everything i need, would include a Ph tester. I did add some nuts at first but after the first week the only thing i did was add city water.

could be too much chlorine or flouride in the city water. distilled is cheap-1.20 a gallon and properly ph'd as well to 7

very true. thanks for all the help
