Grown from seed

Grown from seed for the first time. Usually clones. Green poison week 4 and they look at different stages

Says it 7 week flowering but some looks weeks apart

Come on guys....I'm sure someone can help me??

Help with what? Your growing from seed. Phenotypes…. They won’t be uniform if thats your concern

Seeds are always a bit of a gamble. No matter how stable the genetic line is, there will be variations that are expressed all through the Grow. Some take longer, and their timeline is a guess at best.

Dont go by weeks go by the plant being done. Its not uncommon to have staggered harvest

Those won't be finished in 3 weeks. Shoot more for 6-8 more weeks. Harvest when they are truly ripe, don't go by some "breeder" recommended dates. Some of the breeders out there have never harvested a ripe bud in their lives.

Count days not weeks...I generally plan to run my types of plants roughly 80 days + or - depending on what I see through the scope.
80 days is 11 to 12 weeks.

I rarely have even a short flowering indica fully finish in less than 9-10 weeks as breeder recommended times are a sales tactic and/or gimmic to an extent in my eyes as a lot of people will snag up a pack based on short flower time, but patience is key brother don’t rush harvest and the results will be well worth the wait, I try to let my pistils recede into buds and have a slight bit of amber on an indica hybrid maybe up to 15-20%, on sativa hybrid or similar I’d take them with a lil less amber maybe 10%, but still wait until they tell me they are truly done based on individual strain and not going by the breeders recommended flower times

Thank you for the feedback. My next question. I'm on a feeding programme which you give certain mixture week by week. If the plants look at certain stages !!! Do they all get the same food ? Or do I mix different butt strengths as to what stage they look like?
