Slow seedling
I am concerned with the lack of growth im getting from this auto white widow and the auto New York. They’re both 7-8 days after sprouting and I am just now starting to see new leaves starting in the center. Should I be worried and is there something I can do to fix this?

Trichome Colour
Getting a few of tiny spots of mold/rot on one of these plants in particular... Thinking of harvesting now to stop it getting any worse and affecting the other 3 plants. Are these trichomes looking cloudy enough to be worth harvesting now? Don’t have any better magnification.

False pkging
Is there any way we can start grading breeders on pkging information. Ie if a breeder quotes 7 week harvest but goes 15 on majority of dairies If majority of the strains are false info think the buyers should be aware. I'm pretty confident in 1 exaggerating far.

When do you know when's good to harvest? What do you look for?
This is my first grow that's reached this stage of flowering... we're only on about week 8 I think (wasn't tracking like the last 1) but what's the best way of knowing when they're ready for harvest? I don't think they are , but I want to know what to look for so I never ruin it!

What stage are my trichromes in? (see diary for photo's)
Pistils are mainly brown, but judging from my photo's I'd say the trichromes are still transparent to maybe slightly milky? The pictures from my phone aren't perfectly sharp though, and it's my first growth as well, so I'm not really sure. Could anyone with a trained eye tell?
