7mo baby refuse to eat solid

I started to feed my baby when shes 5months 2weeks. But with only 1 tablespoon per day of puree plain porridge. I didnt follow the 4day rules and for a week i fed her plain puree porridge. Till shes 6months then I started to give her sweet potatoe but she doesnt like it. So i stopped and gave her plain porridge + fish (ikan putih). For a month giving her ikan putih + porridge & serbuk bilis + porridge. Now shes 7months + almost 8 months I feed her 3 in 1 (veggie (cauliflower/spinach) + protein (ikan putih / serbuk bilis) + carbs (nasi). Ive tried giving her broccoli , carrots and chicken but seems like she constipate. But, When she reach 8months later i will try giving her chicken again. Try giving her plain bubur nasi puree again.
