Hey guys, first indoor grow, 4 1/2 weeks in to flower, feminized blueberry, 3 are flowering snowy white and 1is dull white or yellowish, and the flowers are smaller in size but the quantity are good and all 4 look health. Is it a different strain or something else? (Back left and 2nd top view)



Did a flush this morning with water pH at 6.8. Runoff pH was 6.05,
PPM was 610. Hopefully I’m on the right track
