Hi, while working on my project I noticed, that even when using millis function code inside it is skipped every 3-4 seconds. I tried to delete many things and nothing helped. There's pH monitoring, temperature, water flow, distance measuring... etc. I'm using Arduino Mega

It's really long code, is it problem with so much commands sent via Serial??? Sorry for not translating it, but it should give you basic idea.
Thank you for any suggestions.
