dmahny88, glad to see you back and willing to keep on truckin'. As your first grow will be a learning experience, so will your 100th. The day we stop learnin' is the day we die - then, we just go on learnin' somewhere else.

Just to give you an idea based upon my experience, I have a set of plants that are around 30 days veg, a week or so behind yours. I just transplanted them into larger pots, as they had been in plastic Silo cups with drain holes punched in the bottom. I had transplanted them into the Silo cups only 2 weeks prior. With the background out of the way, after only 2 weeks the roots were seeking to grow out of the drain holes; and, upon transplant virtually no soil collapsed from the roots - meaning the roots had expanded to fill the entire cup.

I illustrate the root expansion to show you that your plants' roots most likely have already become entangled. I've read where some growers have had success with plants in a shared medium; however, it is much easier dealing with separate plants, as 1 may require more nutes, whereas the other may require much less. Also, should your plants outgrow their current 1 gal pot, then root separation at that point may be nearly impossible.

I wish you much luck in your continued grow. Continue to soak up the knowledge and building your experience. Good luck!
