DKS AGAIN! What i do wrong???

[Typhon56]

Hello! I have a GBB sling for 2 months. When i got it everything was cool. It was eating with no problem and also molted twice. 3 days ago i noticed DKS symptoms. Im so frustrated, because before the GBB i had a B. Emilia sling and it died from DKS too. What is the cause of this DKS??? Do i do something wrong? I check my animals everyday. Everything is perfect, temprature, humidity, water, food, everything they need.....But why is this happening again? I have 4 spiders and 3 centipedes, and all of them are live and kicking with no problems at all, the thing is that i got all my animals as juveniles. Im really really sad about this situation, and im worried about my sling too. So stressful. I dont want to get any slings again.

DKS is not a syndrome but a symptom. It is commonly caused by harmful chemicals but sometimes by disease and bad conditions. Do you think it could have been exposed to chemicals of some sort? Also, you mentioned humidity and temperature. You do not really need to worry about those. Humidity is often irrelevant with tarantulas and as long as temperatures do not regularly get beneath 60% Fahrenheit it should be fine.
Edit: Forgot to mention, photos?

Firstly, it's dyskinesia, not DKS.

Secondly, dyskinesia is a symptom of an underlying problem, it can be caused by several things including (but not limited to) poisoning from pesticides or household chemicals, bacterial infection (possibly from an overly moist and poorly ventilated enclosure), extreme dehydration, impaction, or internal parasites (this one is unlikely unless you purchase a wild caught tarantula that is already playing host to them).

Where are you getting your feeders from?
Have you or anyone else used any chemicals near them?
Do you have other pets or have been in contact with other people's pets that have been treated for fleas/mites?
Did the affected sling moult recently and did it successfully moult its sucking stomach if it did?

Pics of the spider/enclosure might help us rule anything out too.

Same container? Same decorations? What did you use to clean it?

What symptoms do you mean by DKS? You should describe it.
