Difference value pH in lcd and thingspeak

Hi, I'm making a project about aeroponic. Im using tds, ph, ultrasonic, dht, luxmeter. All the value displayed in thingspeak are the same except for the ph. It shows 0.7 but on lcd or serial monitor it shows exact value (7). I try to change the delay but it still the same. I still cant configure which part the problem are

in showed code i see no errors. :wink:

I agree I could not see any errors in the code either but then I could not see anything that was possibly correct.
