Flowering starting?

the resulting stem length between new nodes is a good way to guide light intensity... too tight needs less, too lanky needs more. trial and error. take note of what you learn works best for that light. avoid the learning curve next time. When you see preflowers, you'll know flower phase started days ago before you could see the growth. figure 3-4 weeks of vege growth remains from that point before it stops adding leaves and elongating stems.

No it has not started flowering yet, just showing its sex......female as indicated by the pistils. Flowering proper should start in about 2 weeks or so.

The pistols you are seeing is the plant beginning to show sex. It is not starting to flower just yet though but will soon if it is an auto. I really think it’s your light, my guess is it may look bright to your eye but humans have a very poor sense in how many photons are actually being admitted because our eyes have the wonderful ability to shrink our retina to allow less light in when light is too much. On the flip side, if you can download a PPFD or LUX app on your phone. Your camera on the phone will be able to measure that light coming in by keeping the shutter and F stop white open and measuring the photons the sensor receives over a 1 second span. My suggestion would be to download that PPFD app and test the light. Raise/lower the light to the heights that the plant will be getting roughly 550 PPFD. And if you cannot get to those numbers with the light being a safe distance away from the plant then the light is junk and you will need to get something different.

Todavía no esta floreciendo. Según la estructura de su planta parece que su luz no es la adecuada para el cultivo.

the light is too far away to get decent bud density they aren't flowering yet but it shouldn't be long mate

Stunted growth might be due to various reasons. I saw perfect plants growing under flood lights with guano enriched soil. There is one "however" though: those plants had proper light during flowering phase. Try downloading Photone app on your phone and measure Lux/PPFD your plant receives.

Its stretching for sure and already flowering? is this and auto flower? as i see your lights state in journal 18hrs on 8 hrs off. i am not sure this light is doing the job i would either lower lights or get something little better looking at your grow journal that u are at 5 weeks, im going to say your light is the issue and its not providing for it
