First Time Auto Flower Grow w/ 3 diff st

Another week down, the Blueberry is moving alone incredibly faster than the other 3, but during this week it finally became clearly observable that all 4 plants have began bud growth. Had a slight nute burn/ph issue problems towards the beginning of the week but seems like it corrected itself. Did a slight defoliation on all plants considering they’re jam packed close together under the light, so any extra breathing space is taken advantage of. Hoping by the time I update this diary next week that the 3 other plants will have a similar amount of bud growth that the blueberry has produced :)
