DWC - New Growth Unknow Problem

[thedudeisback]

So I got this problem in the new growth and i´m not certain of what it could be, it´s 5th day of my 3rd vegetative state, i change the nutrient solution every week while I raise the measures of the nutrients according to the nutrient instructions, everytime i change i make sure i have the PH at 5/6 and the right amount of PPM. This problem started to show 2 days earlier, the roots are not rotten but the nutrient solution is a little exposed to light, that haven´t raised the PPM more than 490. In the photos there´s the details of the nutrient solution aswell the weird leafs on the new growth.
Hope you people can help me out a little

Thank you

the seedlings have nutes already in them for a growth spurt so all you have to do is add water ph to 5.5 and let them get 3 sets of real leaves
