Waiting on base nutes

I am currently waiting for my base nutrientsfrom advanced nutrients to come in the mail... I need to do a water change (rdwc) should i go ahead and change the water and just add the overdrive from advanced nutrients for now?

How overdue are you? What is your current EC reading vs fresh res reading?

Been changing water weekly has been two weeks today

I have been toping off res with reg tap water no nutes.....but I do have overdrive and bud candy.....I know bud candy has no npk value but just listing what I do have....

And plants are starting to show what I believe to be nutrient deficiency

Bit the bullet and changed the water and added b52 and the overdrive.....order for base nutes was canceled by the seller and now I have to reorder
