im trying to get a good pic...having troubles because my pics at too large ..sorry new to the site

im 5 weeks into flowering and cant figure out why my leaves are turning yellow and brown on one plant but not my other!! they get the same nutes, the same water, the same light...everything is the exact same...one plants is perfect and the other is making me nuts!!
I use Fox Farms Nutrients ..everything I give them is at a ph of 6.4...they are under 600w HPS in a grow tent...they have been going yellow on me for 2 wks now...im afraid that I am in root lock...I am trying like hell to get a pic that the site will let me upload to show the browning in between the veins

I am growing 2 plants from seed. They are the same strain ( Green Crack ) and they are the same age! they receive everything the same. One of my plants a couple weeks ago started to show yellow leaves...now they are starting to die off the other plant is dam near perfect...although It seems to just start to show a little bit of yellowing...my buds are nice and and starting to thicken up..lots of resin...I just cant figure out why the other plant went yellow so fast...im concerned that they are starting to go into root lock!

any thoughts or what else can I tell you to help!!

I am not a FF user. I think that's available in the States.
Are you altering the pH at all? I ask because you mentioned it, but you don't have to worry about pH with soil, and you shouldn't be trying to alter it.

Some large photos will help.

yes I do alter the PH after I add my nutrients to the water. my water here has a ph over 8.0 if untouched

the pics I have can not be uploaded due to the size of them!! the site will not let me

Don't mate. You're killing the microbes in the soil.
The microbes buffer the pH.

pH 8 is fine for soil.

I take it you are using tap water. Do you let it rest for at least 24 hours for the Chlorine to disperse?
Also, have you checked to see if you are in a hard or soft water area?

[Harmonybud]

yes I let it sit for 24 hours to de-chlore it and we are in a hard water area

what I don't get is I have a second plant that looks beautiful and it gets the exact same attention

They need to be less than 2mb in size.
