I think Plant numbers 1 and 2 are getting close to harvest. Number 3 and 4 look like they will go a little longer. I am no longer feeding 1 and 2.
They are going to turn out very small. The tallest isn't taller than 50cm, but I am very happy with my first grow so far, number 2's buds are very sticky and have strong citrus smell, I am very excited.
