Give me your opinion on the babies situation..brown tips

so my baby is still growing I would say pretty well, (2 days into flowering) but some of my leaflets have started to get brownish/yellowish spots on them some the size of I would say a dime. I also noticed that the stem has some lines running down them that look purple. Alos another leaflet I noticed that the very tip of it has turned brown, doesn't brown tips mean something?

Might be in need of some nitrogen already.

i dont think it nitrogen. Are the spots brown or Grey if Grey then i would say Potassium. tey adding muriate of potash.
