Hey Growmie, not bad for your first go :facepunch: you want to check the trichomes, a 30x jewellers loupe for about 15$ will help a lot. You’re looking for milky and amber trichomes, mostly milky, some amber. Otherwise, look at the timeline the seed brand provided, are your pistil hairs turning orange? Is the plant not drinking as much as she used to, etc… and then make your call… happy harvest Growmie!:sunglasses::flag-ca:

I don't like putting anything on my plants unless absolutely necessary. Gnats are the easiest to get rid of. Let the top 2 or 3 inches of the soil dry out and they're done. Their cycle is so fast. The eggs die off. The dirt is to dry, so they leave.

Is this a photoperiod or an autoflower? If it's a photo, you can certainly top or fim her but this is the earliest in the plant's life that you would do that. If it's an autoflower, don't even try as it's too stressful for the plant and she won't have time to recover. She's awfully short for her age... try raising the lights to about 18" - it'll help. And I don't see any info on any nutes that you're giving her... I think she could use some good NPK to make her stronger. Good luck with your grow!
