Im growing some Amnesia Haze

i been growing Indica plants for a long time and I thought ill try something diffrent this time

bc im used to indcia im seeing different thing in plant growth

what make me feel a bit worry is that the plant is very healthy but the steams are a bit thinner that what I expect to be on a 3 week plant ( i had some clones not form the seed) on a 7gallon pot

the plant is tall like a bit higher my knees and i did toped once i have a lot of sude brencges and im training them with supercriping or whatever i can do to make a same canopy for the plant

is this how Staivas grow cos i know that grow tall but i like to see them thick strong steams .( the meain steam is pretty big tho just the side brenches thinner that what I expected)
