yes, you can do anything with lime. it just has to be done right in the proper context. lime with little foods or any real buffering materials just lime alione can be an issue is all. but yeah man, you can use it like that certainly. I tell ppl make a lime top coating for flower with added foods. its all good and works. or if your PH is wobbly,sure. turn in a few tsp and call it a day. take time to work though. thats why you mix and blend it prior to flower or whatever so its already broken down and available to start working quickly.
