is it a pollen sack i had a sack grow on my white Russian 21 days into flowering and had to put it down it sucked the rest of the plant had killer nugs on it or are they bananas
everyone needs to see this and try it this way of smoking is the almighty https://www.rollitup.org/toke-n-talk/297165-water-cooled-knife-hits-annyone.html
check all your tips about 2 inches from the top and see if there are any weird looking areas spreed the nug and look inside to see if its been eaten if so track them down and kill them they come in pairs of 2 usually
if you don't see potential in the get rid of them your wasting your food and the plants energy on something that's not going to grow anything smokable so take it off and let something else have the growth that can produce something
sounds like your on the right track you want to water less to get those roots to stretch so 2 times until you get good roots than try for 4 wean you can be ther to watch it that day and if not 3 times till it can Handel it
