Nute burn or Deficiency or What?!

I need help figuring out if this is nute burn or some kind of deficiency please.





I feed my plants about every 3 days with fox farms liquid nutes, big bloom, and tiger bloom sometimes some grow big... my other 2 plants are fine and this plant fell over due to heavy wind shortly before i noticed this, but i dont think its mud or anything like that considering it is showing on a lot of the leaves not just a few.

Check ppm with tds meter. I'd say about 900-1200 is ok. Possibly nute burns due to using heavy concentrates.

I'm having a problem like that to

Imo this might be Calcium deficiency! i see no nute burn!

check out the pics of phosphorus here. GL

Well I looked but still hard to tell but I flushed after I noticed this but I'm using fox farm line up idk I may have given to much big bloom ill take some pics

Big bloom is not going to burn your plants...

maybe were over looking the fact that
its the one that feel over and also if there all fed the same surely they would all show the same signs i say its to do with the fall maybe rolled in something thats causing the burn .

Now we are talking yes this is not just one plants that's this is effecting at least 3

I'm following the schedule that they gave for fox farm products so should I add more big bloom
