How am I doing?...Pics

These are my three, almost 8 week old plants. They're under 120 watts, fan blowing, and I give them a few drops of nutrients when I water (ventilation OK). Not very complicated. Seem to be doing great, their color is amazing (can't really see with the pics). Any tips on how to grow them a little quicker? I feel like they are kind of small for their age...you be the judge. Also, should I change the soil after 2 months, and if so, in what way would I do that? SO many questions, I know...
Thanks! I'm looking forward to hear from you guys

 

Here they are...

 

What kind of light are you using? I'd lower it a good deal, theyre stretching upwards a lot. Also check the roots, they might be in need of a trasnsplant to larger pots. Are you using any nutes? Also when you transplant add a little perlite to the mix to lighten it up, that one looks a bit dense. Since you are using a smaller light, look up LST, or maybe top them to help them bush out. Head over to borders and check out the cannabis grow bible by greg green, good book and itll answer any basic questions you have.

Peace bro, good luck and stay safe.

 

more intense light will help them grow quicker, or lowering the light might help

 

If you're using CFL's, remember 26w per plant, and get them within only a couple inches.

Try some bigger pots, those are what... a pint?
