What causes this?

This plant is in the middle of week 9 and will be chopped any day now. Does anyone know what causes this new growth on the top of the colas?

Foxtails! Read up on it goodbuddy! Happened to me before by dropping lights a little to low late in the game

Last ditch effort of the plant to get pregnant.

Looks like heat induced foxtailing.

Also I know you want to chop that very badly but it still has at least a week or 2 to go.

too much light is another cause

Thanks for the replies fellas.

Foxtail, it's Done, chop it.

I had a certain strain do it on me. Different grows with the same plants.

Lol, no cat tail after taste...
