I think you are correct in assuming it's nutrient burn.
There might very well be thrips as well but you should see them. They are super small and range in colour from black to yellow to whiteish, Can google "cannabis thrips" to get some visuals of what you are looking for and there relative size.
I see your growing Dinafem, I like that breeder a lot. sucks they went out of business from some sketchy shit with the Spanish government.
One note on Fox Farm nutrients, their recommended use is really high and its also why they advertise you to flush every 2 weeks in flower, the salts build up and cause issues. I would look into getting a TDS pen to monitor your EC/PPM and confirm your not over feeding them, it will help avoid flushing in the future. If the nutrients are growing into a soilless mixture the PH might be better around 6.2-6.3 in flower as well. but if its soil 6.5 is great.
Best Of Luck!
