First grow ever

OK got a problem lower leaves are getting black spots? I notice it is getting about 58-60 at night in my closet could this be contributing? Its only on the 2 lowest sets of leaves only showed up day after I water with worm castings, kelp meal, and some barley sst paste.

Well my problem has not gotten any worse I trimmed the affected leaves and trashed them and all looks good! I did some lst and fimming today also added another light so it has 78 true watts all 6500k I guess next ill add a 26 watt 2700k into the mix.

This plant just rolls with the punches I SO HOPE ITS A FEMALE I am going to take a clone as soon as I see a preflower!

Day 31 Plant is doing good I still do not see any sign of sex yall might. There are about 30 secondary branches growing im done topping just going to keep my canopy level as possible from here. Tell me what you all think!

Day 35 got a screen on it I have an auto growing next to which is exploding with pistils atm so its only half screen. I will leave this plant til the auto assassin is harvested from its full cycle 18/6 then throw it into flower. That all is of course once it shows it sex which im guessing will be in the next week!

Sorry that is my auto assassin plant I do not know how to delete the picture this is the correct one

Rock on!
