Cool. Everyone on the forum has been right there. The universe is full of information about growing cannabis, for me, the most useful information has been the wealth of knowledge on growweedeasy.com and the folks on this forum. Something you'll notice right away is the need to know your grow details. Grow medium, pot size, nutrients, amendments, seed or clone, lights and schedule, tent/grow space size, temperature if indoors, RH, PH, watering/feeding frequency. The more detail that's given the better guidance or answer you'll get.
I think those plants look OK, but give use some details.
