Should I be expecting a major crash now???

Lesson learned... Dont be lazy and just add some alk by mixing my sodium carbonate and rodi in a proper ratio if i need to raise it and leave the dosing pumps as they are.

Anyways let me know if i can do anything else to rectify the situation.

no that is fine , generally its not good to raise more than 1dkh in a sitting but if the corals didnt respond negatively then having a higher dkh is fine and will either drop as its used or you can keep it at that level for comfort sake.

it all comes down to how did your corals react, burnt tips can be expected with high alk jumps in acropora but its not a guarantee

you can do a water change with a lower alk salt mix if you want it to drop a bit and there are other ways to lower the alkalinity of fresh salt if it were an emergency but it is not so relax and just monitor the corals
