Cheer's dude, Could this also be a sign of a lack of nute's as well ? couldnt the plant be taking the nutes from the lower leaves to help the upper leaves grow, which is why maybe the top looks like and green and the bottom ones are ' Shite '

You have to know the ph specially in hydro cause it's lower than in dirt.
No nutes the first week maybe 150-200 ppm the second weeek or the
first watering. Ya you gotta git a ppm and ph tester~
