Help with molasses

So I just purchased some grandmas molasses at the store.

Just started my 4th week flowering.

Ive been reading other posts about it and people use from 1tsp to 2 tbsp per gallon of water. Should I start with 1 tsp per gallon?

Should I use a different brand? something organic like going to a trader joe's or henry's market?

Also I read that you have to mix it with warm water first? I cant just pour the molasses in my reservoir?

Please help me.

Grandma Molasses should be fine. One Tablespoon per gallon of water. Start with that yes.

Yes break up the molasses by mixing it with warm water first.
