[focus on this 1]

Hi,

So, its my first grow, the strain is Jack herer , 4 of them.
There are flowering in 12-12 for 7 weeks now, for the first 6 weeks I used growing ferts by mistake , last week I started using bloom ferts 10-54-10.

I am now entering the 8th week and the buds are ridiculously small , refer to pictures.

I am using a 400watt hps light , temp is about 23 celcius and humidity 40%

The plants are about 3 ft tall they look very helthy but I did not notice any improvement in the last 2-3 weeks.

WHATSSS GOING ONNNNNNNNNNNNNN!!!!!!!!!!
