7 month old baby vomits when eating slightly textured food

My LO is 7 months old, she gags and vomits everytime she eats anything slightly textured ( softer than mashed, blended but not liquidy - a bit grainy ) not even lumpy, I tried apples, broccoli, carrots with zucchini, and she had the same reaction with all of those foods!

Please help, I really wanted to try BLW but she can't even have mashed food without vomiting!
