Ok, so you think I should just keep the same feeding and let it ride and see what happens in the next couple days??
I would say so, but get them transplanted out of those pots ASAP as I think the problems will be stemming from the plants roots crying out for more space. You'll only rob yourself of some growth by not doing so, though I accept your concerns over stress.
Personally, I do the seedlings in rockwool and transplant after a week straight into the final container and have NEVER had problems. I am thoroughly convinced from experience that to report anything other than once is fruitless and just poses more problems than solutions.
Other than that, I reckon you're doing just fine there!
