Hey
@vladtms
Maybe it is a good idea to look into your lighting situation.. After finding the light online and checking the price it was only 90$, which indicates that the light is not 600w like the name applies.
Investing in a good lighting solution or upgrading your current one is an easy way to increase yields.
I've had a similar light which boasted a 300w rating and underdelivered. Personally, I recommend quantum boards.
It is hard to see on the pictures how ripe these ladies are due to the light, but I would give them another 3-4 weeks or so, and just see what happens.
Good luck!
