Athosanswered grow question 7 years ago The asymmetrical growth could be just unimportant and due genetics or it could be due stress.
Also, you have slow growth due heat & light stress and probably over watering, plain and simple
Even if you get your plants 2 or 3 feet away from the plants, what's the point? you are wasting power that way, You could put each seedling under a couple of 10 watt led 6500K bulbs 5 inches away and you would save 90% to 95% of the power you are using right now with much better results the first 2 to 3 weeks. Take a look at my current diary weeks 1 to 3.
Also, you might want to learn about transplanting, starting in big pots makes watering the correct amount really hard, as you'll tend to over watering by large amounts, and that will make your seedlings grow really slow. Yes, it's scary at first, just watch a few videos about it on YouTube, believe me it's worth it. The difference in grow speed is significant.
