Day 125 26.9.2021 Cream Mandarine hasn't stopped yellowing, but the buds are forming a bit, so I gave it a chance to show some more. I started to like her yellowing. She's different, she's just her own thing.
You have a very pretty plant going there, some strains grow with lighter color green but low N will show with light green leaves. If you've started flower food they are normally lower in N a lite dose of veg food should increase the N.... unless like you are saying the ph is off... just sharing my thoughts to give you something to think about... good luck and again very nice grow ๐
