The temperature in the tent is in 20-25 degrees and I placed under the water collecting plates a small carpet
Do I have to remove it?
Also I was thinking from the next watering to apply biobizz grow
Should I also stop using activera?

Depending on the ratio you used to mix the allmix with the lightmix, there is at least 2-3 weeks of nutrients inside the soil, you should not be giving biobizz grow or bloom or really anything else right now, some like to use root additives at this stage.
