Diff strains can lead to a plant not eating as much lets say N as another strain leaving more nutrients behind in the media and unused. If its a finicky low feeding plant it may require a touch more runoff to get back to a lower ec that the finicky strain can except as food. I forgot if your running all the same strain or not ..but diff size plants of the same strain can do this as well. just throwing out some ideas..as my golden goat hates its nigrogen and requires xtra runoff every feed In flowering..where it seemed less of a bitch (still a bitch) in veg. So maybe your plants are using less n now that their flowering.
