Weird white spots on leafs need help! cant find mites

So i found these weird spots on the top of my flowers today i looked for mites like crazy and couldnt find anything, no little brown things moving or even webbing! i heard that it might be a nutrient deficiency. Maybe low on magnesium? heres the history on the plant, its a plant that i took over for my friend, it was 3 feet tall when i started nursing it, he never ever used any nutrients just kinda used it and a decorative plant on his window seal. I am using for farmx soil with all of the fox farms growing guide nutrients, i had to cut off alot of the fan leafs on the bottom of the plant because they would all die no matter what i did. Very sad i know but i dont just want to kill it. it looking like it will yeild about an oz maybe less. I just wana heal up this fighter any help on the spots?
thanks alot yall looking to hear from yall soon!
i also attached a pic of the problem.

it looks like i could be a deficiency of some sort im new but i know plants so maybe magnesium have you tested you nurtients levels? and ph levels

i havent, i need to buy a ph scale and nutrient level kit, best place to find one?

nutrient kits by Rapitest are nfg, as is their pH testers, digital, analog and the reagent (vials) If you need to test garden soil send it out to the university. For a pH meter don't go cheap. A little over $100 will buy a reliable meter and you'll be happy you bought it. Don't forget to buy the calibration solutions and for best results use commercial pH up and down solutions.

Only see 2 leaves affected, could ya poss spilled some nute mix on them? Rest of her looks ok, so........ Peace


:thumbsup:

I'm getting most of my stuff off amazon . Com I've seen a lot people use the stuff I am getting and thee planets are beautifully grown I'm only spend like 9.00$ dollars for a 100$ meter on there and the up and down ph kit is like17.00 dollars

I don't know if anyone else can see what I see or if its just the strain but I some the edge of the leaves are Curling upward could be a small sign of too much heat it looks like its mostly on the leaves that have the white spot on them
