Low EC in Runoff

Hello.. Hope you are well.. If the pH is same in run off aswell then she is feeding great and no need to change anything.. If they are nice and healthy then u dont want to push them to much.. Adding mire will obviously raise ur runoff but why wud u want a higher run off.. If they look like they need more then raise ur feed very slightly n dont forget to check ph b4 watering.. Ur plants look nice and healthy in my eyes tbh, maybe give them 18-20hrs light period so she has chance to rest?.. Stay safe n gud luck with your grow.. 👍🍀
