Is my plant going to die?!

[Politieisnietmijnvriend]

I don't think it's calcium. I could be wrong. I guess it is possible that you gave them too much. What strength did you start at? And how did it progress from there as far as doses?

Is this an auto or photo?

Its an auto.
Well i use this guano just as extra, i feed every week 3 times with terra bloom npk 2-2-4 at aprox 60% strength whole the time..i once gave EC 1.0 and i spotted yellow tips next day, so i lowered my watering back to EC 0.7

So what i did was= mix the guano with my soil..then i potted my plants in it.. 4 days later or something, i top dressed a little bit maybe 1 teaspoon
And i began to give it terra grow 3-1-3, all went fine.
Then i noticed some brown spots, and i throw in another spoon of that guano stuff , because i thought i didnt had enough calcium?
Every week i give 3 times feed and 1 water

Shortly after i had a magnesium problem wich is fixed, but i had it on the other 3 plants, not this little fella

in the last 5 weeks(included seedling mode) i topdressed at least twice a teaspoon.(i don't know the doses for it, i just take a spoon and throw it on the soil, its not written anywhere how muchu should use to topdress)
I have 3 other plants, same soil they dont have it, but this one was always the smallest one.maybe overkill on her...

Im gonna flush her tommorow, and hope she will do better and don't die on me yet, she has like +/-3 weeks to go
