Sensei Winter Grow

It's been a couple of interesting days – and as expected yet another curveball! 😅 The last week and a half's growth spurt (23cm / 9") seem to have resulted in both cal and mag deficiencies – and as we have pretty hard water here I though that it would be fine without supplements. But that doesn't seem to be the case here – so in todays feeding I gave the girls a boost of CalMag hoping that will resolve the problem. The stems have gotten quite thick and sturdy over the last couple of weeks – and the height difference between the plants has also become more prominent; 51cm/20" vs. 36cm/14.2". First I just though it had something to do with the different strains as Sensi Seed says that the Afghan will be smaller than the Amnesia. But then I noticed that it rater seem as the plats to the right in the tent are higher (looks like they're stretching) while the plats to the left seems to be shorter and more bushy; and the thing is that that are plats from both strains om each side. Girls to the right = Amnesia #3 & Afghan #2 Girls to the left = Afghan #1 & Amnesia #2 So I started to think of what might be the difference between the left and the right; - The lamp is centered so there's no difference (although the taller ones now are closer to the light of course). - The fans are on a diagonal so if they where the main source for the inconsistency it should look different. - They're all have gotten identical feeding, soil, germination etc. - The only real difference between the both sides are that the right side (where the plats are stretching hence taller) is where I have the have the incoming went – and the intake is passive and generated by the pressure of the outlet fan/extractor. So this makes me wonder if it might have something to do with the plats to the right are geting more CO or more more humidity (65-70% outside the tent – 40-50% inside) – but then again I do have to fans that do create a lot of circulation for such a small tent. So I'm not certain of what the difference is – but I have ordered a couple of CO-bags to se if this has any impact. Do you have any thoughts on what it might be? Please drop a line or two! --------------------- There's really something new every week – it keeps me on my toes and I keep on learning new stuff. It's still early this week so we will see what happens next; I'll probably do an update in the end of the week. Wanna bet that something's new come up until then? 😜 --------------------- UPDATE 12/2 So I started to see signs of different deficiencies on the same strain that had the same treatment – and I couldn't first figure out what was wrong,. But today I noticed that they also showed singed of being to dry – so I watered them and focused on macro nutes; that's when I noticed that the soil had gotten so dry that the new water was just running on the surface, down on the sides and out of the fabric pots; so they have probably not gotten as much water and nutes as they should for the past couple of weeks. So today I watered them in small portions several time to make sure that the soil absorbed the water and nutes. I'll keep a close eye during the weekend to make sure that they recover.
