First of all, are you in soil or doing a hydroponic grow? If soil, forget the pH of your water, what you need to know is the pH of your SOIL. The soil will change the pH of whatever solution it holds to the pH of the soil as that solution sits in contact with it. Run-off is no indication either. I agree about the cal/mag, and watch the new growth for any signs of the blotching.
You need a good pH pen as well. Even tho pH is very forgiving in soil, so much so that it is pretty much a non-issue, it's always good to be able to eliminate pH as the problem with some assurance of accuracy. They cost a bit, but they are a one time investment well worth what you pay for them.

its the fading of the leaves you will start to get like tiger stripes fading of yellow.
use calmag with your food mixture at like 25 to 30% . i would go half strength if they are like 18"or more tall

the fastest way to put Mg into your plant is to spray with a solution of 1tbsp Epsom salts/gallon of water. I saw bleached interveins. you can get Mg from an addition of dolo lime also but it'll take longer to work.

yeah sorry forgot to mention it is soil... got a ph pen... I put some soil in a glass with ph neutral water mixed it up a bit and tested came out at 6.5 pretty much.

here is another pic... can you see the little plant in the middle,,, that's not grown for weeks,, cant work it out. green and looks healthy just no growth.

the cfls are no longer in just the 600w hps

Kinda hard to judge leaf color with those LEDs on. It isn't a pH issue then I'd make a solution like dannboy said 1 tsp/gal and either foliar spray it or water it in. keep an eye on new growth for any further signs of it. (Ahem....manganese....aaallrighty then.) Those charts are as bad as WebMD. Don't look for the most esoteric, look for the most common and logical.

Maybe try phosphorous, and then give it some manganese when that doesn't work, lol, I kid. Good luck with your grow.

Edit: No offense taken or intended. How can anyone get offended, its WEED! I am lol'ing the whole way.

Dude, forget the manganese. That is HIGHLY unlikely to be the problem. It is MUCH more likely to be a cal/mag issue, but be careful. Don't exceed the recommended dosage. Ca and Mg can lock each other out in overabundance. Follow the directions and you'll be fine. With nutes, less is more.
