AsNoriuanswered grow question 2 years ago they all stretch out , i would consider supercroping all tops, think were you will fall them, that way all canopy will be even
your inner nod spacing says its too weak light for them, so otherwise all bottoms will be pure popcorn air
give small chair or anything, for that smaller girl if needed
now with is it same strain ? you have two brothers or a friend with couple, do you all look the same ? that's the answer to your question ;)
Happy Growing !!!
