One plant with increasing brown spots any help appreciated

cant seem to pin poin the cause of this same nutes and water as every other plant i have done

Almost looks like a fungal infection. Thats were I would be looking for answers........It could possibly be a calcium issue but I still would lean toward a fungal issue.......

its a micro of some kind, its happening at the top leaves first right? usually when you have a nut deff, its not because you arent giving them the right amount, its usually because your ph is off or lockout has occured. check if the runoff is an intense color and check its ph. thats my guess, ph is off in rootzone. odd though.

its like the middle leaves not new growth not bottom but thx i dont know why the ph would be off i check it every day

well i decided to flush her with 5 gallons of water with clearex at 6.3 cant hurt and i figure its gotta b lockout cuz my humidity is like 32% and all my plants are crowded together but the spots are exclusive to this plant ill keep yall posted she's flowering like a son of a bitch its my 5 oz per plant bubblegum strain she is a big yielder
