Will a raised pH make leaves light green?

Hi all,

I'm growing a Female Seeds C99 in a dixie cup sized hempy and it's been 8 days since sprouting. I've been adjusting tap water to around 5.8 pH and have been watering several times a day until the roots hit the rez. The plant has a dull light green colored look to it:

The camera is actually saturating the color and this picture makes it look greener than what my eyes see.

I've thought that it could only be the pH doing this, so I checked the run-off and it was higher than what I was putting in, close to a pH level of 7. I took the perlite and vermiculite I'm using and put them in separate cups with water to test them individually. The perlite moved the pH up by .5, while the vermiculite moved it up 1.3. Could this be causing the discoloration? Should I adjust the pH according to the runoff to make what's coming out of the bucket 5.8?

Keep adding ph'd water to bring the PH down in the bucket or you could end up with a lot of issues ( i learnt that the hard way), 5.8-6-2 is fine in hempy, from what I've been told by other hempy growers here, try that first maybe do 5.5 ph to bring it down? are you adding nutrients? they won't take nutrients in if the ph is too high or too low. so try and bring run off ph down to low 6's minimum, I'm not an expert at this, but I had a lot of issues first time round, hope this helps and happy growing mate

Thanks for the reply, htidwelshy. I'm not adding nutes yet, as the cotyledon are still on and looking green. I'll drop the pH in the water that's going in to an amount that will be right when it comes out. Cheers!
