Taco leaf?

I had problems with drooping plants after i transplanted so i flushed with low ppm feed and they seem to have bounced back pretty quickly temp and humidity is 25-25c and around 70-75% i dont know wether they look healthy or not i did a little topping and bending to 2 of them but the other 2 are still having problems one of them the leafs are tacoing and the other just seems to be stunted i checked my ppm runoff and it was nearly double the inflow(500ppm) so i flushed again with 250ppm if this is the problem then why do they look better than they did when they looked poorly? Does anybody think they look ok?

They look pretty pale to me like they are hungry but they are young. 500 out for runoff isn’t bad I would be feeding a balanced nutrient at say 300-500 at most and make sure you get runoff every watering. What PH are you feeding at?

Purple stems, maybe and paleish. Maybe up the ppm.
