Discoloration throughout plant's old and new growth...

[Abbazabba85]

I've got this yellowish/light green discoloration throughout the plant. I'm also seeing some light brown spots on a couple of fan leaves. No curling on leaf tips or much droop....Nitrogen issue? Or maybe a Cal/Mag issue? It's a strawberry cough in FFOF and perlite, roughly 70/30. I have a wedding crasher and a do-si-dos in the same set up with same soil and they look great...I water them the same and all that as well....any help would be great!

He mentioned he had 3 genetics so they aren't the same cut 2 of the 3 are doing good just this one so I assume it could be a deficiency looks and sounds like cal mag....are you watering with R/O and what nutrients are you feeding

Your pH is off.

Make sure you're not giving them too much light. Probably one of the easiest things to check off your list of potential problems. What's your lighting and at what height?
