Help quick

I need help with my plants the stems are goin purple and this are little white bugs in the soil when i water them i will take pics n post them any advice would be great

are you looking at fungus gnat larvae? Stems growing purple can be normal or phosphorous def or cool temps...several more things.
It is pheno specific.

As DMD says, red stems are usually a sign of stress unless the strain is bred to look like that. I have some Ice Cream on the go just now that is red.
You need to get those bugs out of there though. Your plants are the only food in there so when they get hungry there will be problems. Is the plant in flower yet?
