Their is a little water residue from recently using tap water and hydrogen peroxide for a dirt mite problem that was solved with ease but next time with not used tap water, but to get to the point this plant has had this pattern since I can remember and throughout its life it has fluctuated in the paleness to greenness it has had but other then that it’s been healthy actually their was a case of yellowing to almost a white tip on one of the new growth leaves for a period much love
