Sensi star - the star of my tent

Another week has passed and the first month is coming to an end since the light was changed from 18/6 to 12/12 (11.5 hours of main light + 30 minutes of pure Far Red). The top floor is a little jarring because of the temperature, but there is nothing to fix it - it all depends on the temperature outside (and when I myself melt in the room like ice cream, I don't think you can make it cool under the lamp). Plus, this time the stretching of the plant turned out to be strong enough and the lamp is exactly at the same level so as not to burn out the chlorophyll on the tops of the buds. The appearance of fox tails is possible, but to be honest, apart from aesthetics, I did not understand what they are bad about - it seems that all the buds are curled well. But this is still just my guess, and at the moment the Star is overgrown with leaves again, the light penetrates downwards not so confidently, in 2-3 weeks there will be a second defoliation. I will not cut the bottom for sure - there is nothing superfluous left, and at the moment what is there compared to the tops does not look so impressive. On the other hand, these shoots appeared much later than the tops and they have every chance of becoming a good small bud.
