I was gonna do 1 every 2 weeks and see how that goes at 25%. But now im just wondering if i should just do like you..50 % once a week. Any of the ways ive changed it up i havent noticed any ill effects. Also curious if changing more frequently like once per week at 50% and having a decent amount of plants is counterproductive as the plants help clean water and id be removing nutrients the plants need?

I think you should find the routine that works for you. I would do at least 25% and let your stocking level determine if you go any higher. The closer you are to heavy stocked the closer to 50% you should be, IMO. Whatever you decide on, do it every week without fail.
EI dosing ferts makes it necessary to do at least 50% for me. I usually do a little extra because I tend to overfeed and this causes my nitrates and phosphates to climb a little. Plus, in my 75g I'm heavily stocked. There is nothing counterproductive to plants that I am aware of doing big water changes. A large portion of planted tank enthusiats do it, especially the hi-tech group.
