Dude,trust me,any of the response given with too many detailed info like EC/TDS,foliar sprey or emergency flush are gonna make you worry more about a non-important subject.Your plant looks great and lively.Just don't break its move.Grow nutrients seem a bit high for this point of flowering.I would lower it to exact ZERO gradually.Other than that,I see no signs of deficiency or a problem.Of course,I'm not an expert but I get experience day by day,I read a lot about growing marijuana.What I learned up until now is that you should only pay attention to TEMPERATURE,HUMIDITY,pH and AIR CIRCULATION.If these conditions are met,chances are you will have great buds.No need to confuse your mind.I see your humidity is good at this point,day temps are very good and night temps are good as well.My Mexican Airlines grow just finished yesterday.If I showed you how it looked towards the end,you would be highly surprised.All leaves were dead but I know that it's a pretty normal thing.My friend watered them with pure water ONLY ONCE in their lifespan and they drank all the nutes left in their leaves.But I knew,they were super healthy until that point and they still grew super buds after afterwards.As experts frequently say to me,it's just a weed,no need to worry.If you meet TEMPS,HUMIDITY,pH and AIR CIRCULATION right,it'll already reach its potential.Other than that,it's just a matter of science.We are not scientists,so we grow weed the way we like.If the plant looks good,don't worry.If it has problems,it's not going to be hard to notice.
