First Time Auto Flower Grow w/ 3 diff st

Everything going good, started feeding with Tiger Bloom as flowering has been underway for about 2 weeks. Moved the plants to my main tent under a 600w HPS and of course they are loving it. Unfortunately had to kill the slowest growing plants due to space (1x amnesia and 1x blueberry). So now left with 2x amens is, 1x sweet cream, 1x blueberry. The blueberry is accelerating in growth and age far beyond the other 3, not sure the reasoning (might just be better genetics or the strain itself). It’s the only plant so far showing true signs of bud growth and is certainly taller than the rest, but the other 3 are still growing strong and shouldn’t take more than a week or so to catch up to the blueberry. Did some minor defoliation as well when the move to the new tent occurred. Will report back next week :)
