Help pleas

[Huawoi]

Ok my previous reply didnt get posted, sorry for my late reaction. I bought myself a ph meter and got these results pic 1 is the sick plant and pic 2 is the shiny one in the back. I also bought 2 products that may help since theres alot of ph in it. Got pictures of it aswell with first the front and after the detailed info on the back.
Should i give it to them or will this make it even worse?

Also an update on how its looking.

Hoping on a fast reply. Thx already

.... no, on the pool pH chemicals!
...pH on the better looking plant is fine, but the bad looking one is just what I expected-- too acidic,... this far into the game, garden lime isn't going to act fast enough, so a pH up product is needed to adjust your feeds,... meantime, a flush of about 1.5-2 times the volume of the pot will help reduce the acidity,...in the last L you pour in, add 1/4 strength of the 4-6-6 feed,....
.... the other feed is a strong grow formulation, which is wrong for the plants now,... 4-6-6 is better, but still not what you need,... a dedicated bloom formulation, high P-K values, low N,....and some Ca-Mg supplement....
... as you're finding out, this is not a simple thing to grow quality MJ! ....try and find some good books on this subject, and learn some fundamentals about nutrition, soils, pH, etc.,... otherwise, you'll just be rolling the dice, and chasing one fix after another.... Cervantes and Rosenthal are very good authors,.....

Hey Waira,

Thanks already for the usefull information!
Now i flushed the sick plant and gave it 1/4 of the canna flores, in the hope she'll be ok.. But i thick it would've been to late :/ anyways there is hope! Now i also putted the ph meter after flushing again in the sick plant picture of that underneath here.
And also i noticed the good looking one is getting spots on the right side, the 3th plant is stil in middle of sick/Well Anything i should do about those 2 or should it be fine with the extra nutrients i gave?
