Fellow farmers advice

[Wildme]

Hello fellow farmers, have 4 plants about a foot tall
and are noticing some drastic changes in a couple.
Any advice why?

Are they the same strain? Are they getting the same amount of light? It is hard to tell from the picture but I do know for sure different plant strains require different nutirient amounts. What size is the pots they are in perhaps they need a like 5 gallon planter so the roots can expand. The good thing about water growth easy to check nuts plus faster lol. Sorry I could not be more help

They aren't the same strain, they do get the same amount of light. Gonna plant in the ground
Tomorrow so hopefully they will get all the room they need. Thanks for the advice bro. They are in
small pots for there size probly a gallon an 1/2.
