Just looking at them, I thought you done quit feeding them, if your feeding them, keep on feeding, I don't use nutrients, but when I did, I'd quit feeding when I saw some amber on the calyxes, then start flushing.
But the molasses will help kick your soil in gear.
I grew 3 of those SweetTooths, so for, and 2 of them had those pretty purple leaves, just like yours.
And yeah by harvest time they will get larger, and harder too.
I'm gonna try to grow 8-10, more of them out in the woods pretty soon, when the weather gets right.
But you've done a great job, with your plants
Very nice.
