algamic is pH 7.5+ , actually when it goes into your soil it could mess it up, you can see if this is the problem by measuring the water that is going out of the pot instead of going in, it should not really be more than 6.0-6.7 otherwise you could have a problem. for me it looks like the pot is too small for the plant, this i can see from the purple stems and the strange wilting symptoms , change the pot and see if you can save it . Hope this helps ! 🚀
