Trust me....46 days or 21 days....matters not.
They will triple in height during flower.
They will continue to grow at about 1/4" a day now til the end....thats if you have any MH present.
If not, look for 1/8 - 1/4 inch daily from here out. DO the math and see what you have. Dont get caught by surprise.
You have at least another 4 weeks????? of flowering? thats another 28 - 30 days...
at .25 inches a day....thats another 7" :D
They arent so easy to bend once they have those thick stalks. Some wont allow it...so, just be prepped and ready at the helm.
