I'm going by hairs until my gf has the motivation to find her old micro. I don't want to spend $ for a new one b/c i have a 6mo daughter, i am paying all the bills while my gf looks for a new job--long story short, her old boss is gonna hear from a few attorneys and civil rights board about her release while on maternity. I also am guestimating by the breeders info on 8-10 weeks flower period. I'll be harvesting @9 weeks.

As for watering period, you can guess the days, but plants feed at different levels at different times. I use a moisture meter and have come to trust it as it is always consistent and it's proved me wrong many times over the old "lift and feel the weight" method. Of course, the "lift and feel the weight" method is good too, but at times (like this) you don't want to over water a plant but don't want her too dry either. So, I water when they need it, and not till, and at times that could be 2-4 days between waterings.

Okay, one complaint: the buds are so sticky that they are hard to roll up.

In my experience it is the lack of humidity, not the lack of water in the soil that brings out the trics more...of course excess humidity can be caused by overwatering pots and it evaporating into the grow room
