Growforme

I am new to all this, I have Chronic pain due to a Spinal explosion, low spin shattered. I am at week 2 I started with 5 seeds and 3 Germinated, planted in a starter mix with nothing but spring water for about 3 weeks, they are a bit tall, the light was to far away and 2 grew tall, I lowered the light and they are now looking much better, Rocket Seeds are where I got them. I am watering as needed. My light timer is 18 hours on and 6 hours off.
