Was thinking maybe nute lockout but leaves don't appear gloss and dark green ? But then again WTH do I know which is why I'm here and thank you all for the assist
very new to this so excuse my ignorance. Initial two serrated leaves yellowing out see picture. Thought maybe overwatering so stopped watering for three days and checked with moisture meter they were pretty dry. Added moisture to green zone on meter. Then thought lack of nitrogen so mixed up...
