Every strain is different when it stretches in flower. supercroping if for veg time only.

Try your mother down. Once you get the tie downs in place don't push it. Just keep pulling them down alittle every couple of days. You don't need it much cause after week 4 of flower they will not stretch much more. Unless you have a late bloom strain.

Next time you know to start them earlier.

Oh, very nice grow. Your going to be very happy in a month. Layed out on a couch but very happy.

Keep us up.
