flaxseeds

Hello! I was wondering if 1-2 tbsp's of grounded flaxseeds a day would be enough omega 3 fatty acids or if I should take algae supplements as well?

I realised that my diet is 60% carbs, 30% fats, 10% proteins. Don't use any oils. It all came from natural peanut butters, almonds, chia (I eat like 4 tablespoons) and flax seeds (about 2 tb). Is that a problem. I want to put on some weight and keep healthy.
