What kind of nutrient deficiency would cause this kind of patchy discoloration?

i believe ph is somewhere between 6 and 7... which i know is high for a hydro setup. i only have a cheap aquarium ph test kit and it's not very accurate... it's difficult for me to make adjustments with any kind of confidence. i have a digital meter in the mail so that will help matters... i'm just crossing my fingers until then.

Until you get your ph until control don't worry about anything else.

You are far enough off that it can and probably is causing the problems you see.

Adjust the ph and then we talk buisness

Try some seaweed/kelp extract.. looks like a nitrogen deffiecency from here.. but it can be a number of things added up.
