1st grow - Stone and CBD

Ok, here we go, week 3 - still vegetation stage. Bad news, I managed to bump my hand and drop watering can on one of my girl's head. It broke about 3cm from soil and the top part dried over night. Had to cut her at the break but as the lower part still seems green I decided to let her stay in the soil and room until drops dead. I watered her a bit more and I am holding my fingers crossed to see her recover. For the rest of them, they are starting to stretch. My ML No. 1 is the most vigorous one. She is closing on 20cm now and grew two branches from her fimed point. I am tying her down and letting her grow horizontal. ML No. 2 is going well, she is growing although at slower pace than her No. 1 sister, reaching about 15 cm. My ML No. 3 is unfortunately the one who got knocked so she is now about 3 cm high. Moving to my Black light girls, they are all approximately the same height, about 11 cm. Except one of the BLs they are all LS trained (I will do the same to BL No. 3 when she grows strong enough, she seems a little bit on the weak side). I have also changed the lights in the room now, moving from FL to COB LEDs. The illumination jumped very much now and that might be the reason why they started to grow much faster now. I have finally received my 3-in-1 pH digital meter so I can asses the watering pH as well as PPM (EC) of the overflow (i.e. the water that comes out of the pot after watering). I see I didn't get my watering pH just right, instead of 6.4 (as I read on my pH strips) it is actually 6.6. A bit on the higher side so I might consider getting it more acidic. I will see what I'll do). On the other hand my PPM (EC) are very high. The EC reads 3.5 and my PPM 2630, and after watering and good overnight sleep it now dropped to 1805. My run-out water also lower pH than the watering one does, it stands at 6.1. All in all I can say that my babies are growing nicely, they are stretching by the day and gain about 2 cm in 24 hours. I have no idea if that is high or low but for now I am satisfied with that. And the big news (at least for me) is that I am starting to smell them (it). I think my ML No. 2 is starting to have that heavenly scent. I just noticed it the other day when I moved them around and when I came closer to smell it was mostly gone, so I guess there is not much of it yet, but HAHA, going in the right direction. Any other news to report, oh, ok, Until yesterday (i.e. day 31 from putting them in the pots) I used 176kWh of electricity and spent 30.85 EUR for that. Better be something at the end. To get to this number I ran lights, heater, fan, and extraction fan. Lights are on 20/4 cycle, heater runs when needed, fan runs constantly, and extraction fan is on 3 minutes and off 20 minutes 24 hours a day. Update, Saturday, 6.March 2021 - Now two of my BLs (1 and 2) are also emitting a slight smell however, ML No.1, the biggest and most vigorous one is still without one. Waiting :-)
