looks like iron deficiency.. PH is the normal cause of this, what is your ph at?
Im not sure of the pH because my meter is not calibrated but im waiting on buffer solutions to fix that. I use water from a local stream and it doesnt seem to affect the other plant. I was thinking it could be a magnesium deficiency. I will add magnesium and iron with the next watering and i'll post again if the problem persists.
