StuG's Sensi Seeds Black Lights CBD Auto

So, my days are a little messed in terms of regularity of posting BUT the girls ARE 23 days old so, that's week 4 including germination, and week 3 of veg. I think. It's going OK I think. I now have 3 bears rather than 3 plants by which I mean, there's a baby one, a mummy one and a daddy one! Or something like that. I have retained runty girl, and she's improving, and one is going nuts and the middle girl is doing OK too. Surely it cannot be THAT hard to have 3 the same size given they all started the same, are in the same pots with the same lights, in the same medium. Or is this just a 'dirt growing "thing"'? No nutes yet - plenty left in the Biobizz Allmix I think but that said the plan is to introduce Fishmix this week now we're close to flowering, and then obviously it'll be Bloom and Topmax to the finish! Oh, and these will run with no LST or anything else other than basic defoliation from the bottom up, and some leaf tucking here and there. I had planted these out with the view to LST'ing hence the offset in the pot but have since changed my mind (and may again in the next day or two!!) The reason is simply that this is my first grow with this genetic and I want to see what she does before I try altering her, so I am not expecting huge yields, but I am expecting to learn and am recording the progress so I can hopefully improve, when it comes to running this genetic again. Thanks for reading. 😀 Edit: I'm using NOTHING but harvested rainwater for the girls, although I only started that at week two, when the heights were already different between all three, and runty girl was already properly runty, so, it's not the consideration in terms of analysis when it comes to trying to work out why they are so different. Anyhow, yeah.... rainwater because my local hydro place said "try it - it works" so I am. 05.01.2021 My rainwater is checking in at PH 6.2 so that's kinda nice. I know the Allmix will buffer but still. With my last grows I knew the mineral make up as it was on the bottle (I used bottled spring water) but I feel less confident using something that without testing, and would likely change day to day anyway, but then nature would be random anyway right?
