Looks like a little bit of nute burn...Are the leaves with the larger brown spots lower on the plant, and could it be a possible splash of nutrient solution on them? Lower fan leaves that don't receive enough light will start to wilt and die as they realize they are kinda useless not being able to soak up enough light, overnuting accelerates this process. I'd say give it straight water for a week or so, you'll probably see her start perking back up a bit. You've caught overfertilization early if this is the case, so going light on the nutes once you start introducing them again should balance things out. If she is looking worse after a week then take some more pictures and get back to us

that bottle doesn't know what you are growing...so yes those are the "instructions", but it can't dictate how much nutrients are being absorbed by your plant and what is left in the soil. Seriously drop it to nothing but water for the next week, your soil doesn't need anymore nutrients added at this point, its got plenty to go on for at least the next week if not longer...and ease it back in with 1/4 strength.

i would agree, it looks like a salt build up maybe caught up in the perlite that gets soaked with nutrient and then dries out the water only giving good oxygen to the roots but the next time you pour your solution through the perlite adds salt every time from the dried solution in the perlite, that is why you use vermiculite in a neutral soil with no nutrients in it, the trick is to give just water a few times during the plants life, double any flowering boost the last 3 weeks for two weeks and water only on the last week.Looks like a little bit of nute burn...Are the leaves with the larger brown spots lower on the plant, and could it be a possible splash of nutrient solution on them?

make doubly sure that ph is set at 6.5 in soil, if it has been higher or lower the whole time then the plant could be overfed with certain nutrients causing burn while she has been underfed other nutrients causing undernourishment.
if i knew the ph of the feed you were giving her i could probably tell you what mineral she is needing to gain or lose.
and remember that in soil ec in solution does not matter as much as in hydro.
but what i will tell you is a plant must have 3 main key minerals, Nitrogen (N) Phosphorus (P) Potassium (K) so the chances are the problem lies here, not in any of the other smaller minerals, which means the ph has been lower than 6.5 and the plant is lacking potassium, calcium and magnesium.
if it has been higher than 6.5 it will be lacking manganese, iron, and boron.
make sure the ph is checked when the solution is at grow room temp, the same temp as when it sits in the plant pot.
and remember that a 3 part professional nutrient MUST be added at the exact rate and is usually only used in a neutral soil like canna terra professional plus that has only enough nutrients for a week.

Your nutrients won't magically make the water you are using an exact PH of 6.5...you have to start out with water at that PH if their solution is that PH, for it to remain at that PH. It's what we learned in chemistry way back in high school. Same applies here. Take a 50/50 solution of two liquids, one at PH 0(pure acid), and one at PH 14(pure base), combined they make a ph 7.0 solution:

all nutrients have a ballanced ph, that is why they are labelled, soil, hydro and cocoa, i am using hydro nutrients in soil just now but because hydro ph is lower than in soil i have to use roughly 3.5ml of ph up, per 10l of nutrient enriched water to get it to adjust instead of a few drops, the nutrients in the 3 solutions are the same, just the ph is different.
you must get that ph at 6.5 now !!!!
THATS YOUR PROBLEM SOLVED.
flush first 3 amounts of water per pot size, eg. 2 litre pot, 6 litres of flush water, and then the plants will make a quick recovery when you feed at the desired ph.
