Do you change amount of ferts with a tank upgrade if plant mass stays the same?

Hey everyone,

Upgraded my 30 gallon to a 55g with the Petco dollar per gallon sale and I was wondering if I should change the amount of fertilizer I am using if the plant mass has remained the same? Sorry if this is a stupid question...

Thanks

Yes, you want to keep ferts in the same concentration but now you have 83% more water to do. So take what you were doing on 30 and multiply x1.83 to get same rate.
