Not sure where my pictures went so i upload them here again.

Your tree has an Iron deficiency.

Thanks silica! i knew it was something ill try and transplant it into a slightly bigger pot, but could the defiency be due to a salt buildup? Should i flush the soil ?

I did some additional researchresearch on iron defieciency and it seems that it might be a ph issue coupled with to "tight" soil which would also explain why it drains slower than the rest of the citruses so ill add some perlite and repot it and ph down the water as i know its slight above 7 already.
