This can't be burn again... Has to be lack cal, mag or nit ... I flushed em a week ago . gave em very very light feeding with super thrive two days ago and now this.. Need help
It looks like a ph issue to me and multiple nutrients are getting locked out OR it looks like they are really hungry. Where was that leaf taken from? Bottom or top? Do you have a pic of the entire plant?

I don't have one atm ... Plant looks fine just picture plenty leaves looking like the one I posted.. Plants are standing tall look healthy just discolored
If you're tent is running a bit hot 80F+ you may have to increase the watering. If I were going to grow in soil I'd get a hygrometer made for plantpots and soil. They run at about $5Can.
I realize that these things can only give you some idea on when the plant goes dry but it's better than not knowing.
I rely on pumps, timers and relays to do my watering for me.
Mine get this way when they need cal mag. I usually use flora nova one part nute and never had this problem. Now that I use the grow big and tiger bloom they are discoloring
