If anyone experiencing the same problem here is how I solved my problem:
So I found out that yellow-ish foams caused by hydroton. I rinsed them well before I use em but it seems that wasn't enough. Since there is no root development I was able to remove the hydrotons. I cleaned, rinsed them again. literally washed them out 500 times also soaked them in 5.5 phD water for 24 hours. And then I changed my air pump got a stronger one and put it OUTSIDE the tent. it was inside before. Also changed my air pipes with black air pipes. Now there is no smell, no foams, no cloudy water everything seems perfect although my ph is still rising. to figure it out ph rises I got another tank, I run them with the same nutes but I didn't put any plant in it. ph was still rising, I noticed something water level was going down slowly even tho there are no plants in it. and then I found out when water evaporates ph rises. I believe when roots are developed completely there will be no problem.
