Small Buds on Terrace grow

Hey guys,

This is my first post on here, im a new grower and its been hard trying to select a community to join, however i find myself using rollitup mostly so i decided to try and settle down here.

This brings me on to my first post:

I got 2 Plants both Easy Sativa Auto by Female Seeds. They are around 4 weeks into flower and the buds are really small.. I means really small, Im not entirely sure if I should be worried or not.

• Plants are around 4ft
• Im using bloom fert & 0.1ml PK 40-20
  
• Plants get around 7hours of direct light a day
• I recently put plants in darkness for 12hours to try and increase bud growth
• Plants did have thrips infestation in Veg

The trichomes are around 50-60% amber which is making me think they are ready for harvest.. Which looking at the plant would be a yeild of maybe 10grams per plants :/

Any suggestion would be great in terms of when to harvest. To be honest i am not concerned with having a small yield this is my 2nd try at growing so I know things will improve over time. I just want to be sure that when i do harvest its the right time!

Thanks so much heres some images

harvest when the stink is so much you're at risk for serious jail time.

Im over in espanol, so its legal here! But theres not that much stink right now!

It's only 4 weeks. Auto that I ran in the past went 8 weeks so I might be ok. Just let it go until the leaves start yellowing. Good luck esay.

The thrip infestation will definitely effect your yield, but you have a long way to go yet.

She is looking a little heat stressed. Your flowers are going to look smaller. It's a sativa, so the buds take longer to put on weight. Looking good for your 2nd time. Just be patient with your sativa and you will be rewared. Your looking at around 6-7 more weeks of flowering before she is ready.
