Cinderellas and a ( TRICOT ! ) Lemon Kix

@Mrs_Larimar, it’s at 55% and 35cm right now. not too far off from your recommendation

@DomForester, I also checked the Dutch Passion description for Auto Cinderella Jack, and there are already a few hints that this plant naturally tends to stay compact. They describe her as compact, medium-sized, and mostly average in height. They also mention that she is best grown indoors in a SOG setup, and that because of her compact nature, she is not really ideal for scrogging, bending, cropping, or super-cropping. The larger sativa-dominant phenotype seems to be more of an exception. So in this case, I would not blame the grower too much. It might simply be the genetics doing what they are supposed to do. In a SOG setup with many small plants, maybe even in 0.5 to 1 liter pots, I think this strain could actually be great.

@DuschkabinenGrow, yooo thanks for putting so much thought and time into this! On light intensity: It was my first run with new lights. Might have been a bit too cautious but I did have a feeling the manufacturer guidance was on the low side and they could have used more during veg. On feeding: I skipped BioBizz Grow entirely because I hadnt even started feeding when they began flowering. I had 2/3 dose Monster Bud Mix (slow release full cycle) in the soil so I thought they’d be getting enough N by week 4 and went straight to BioBizz Bloom. I believe I started feeding CalMag too because leaves showed definciency. But I’ll definitely have to pay more attention to dosage guidelines - I realized (too late) that I went a bit over. On water: Im pHing to somewhere around 6.0-6.4 every watering (measured and adjusted after adding nutes of course). No idea about minerals except I think it’s supposed to be somewhat “hard” water. I actually prefer using water from my rain water tank when there aren’t three heatwaves in 2 months… On soil: This is a big one and I need some advice here. Ive been using veggie garden soil from the garden center and add around 10% perlite. I did have the feeling that it turns pretty dense after watering for a few weeks. Any suggestions on how to improve and mix up something that stays more airy? On genetics: I agree partially. I should have read the info earlier and not LST’d her that hard. But the untrained one yielded even less… I’ve grown autos with similar breeder info before (Short veg - although Ive never seen 4 weeks - medium height, etc) and under worse condition that grew 50% more biomass then these. Im currently cultivating my first batch of compost and am about to order the basic stuff from Biotabs to try a different route. Any other suggestions welcome! Again, thanks for your super constructive feedback! Much appreciated!

@DomForester, Feeding: I would say they probably did not need any fertilizer at all. The Monster Bud Mix and the soil should already contain enough nutrients, including magnesium, so I do not think CalMag was really necessary here. Soil: I have not found my perfect soil yet. Well, actually I kind of have, BioBizz Light Mix with peat, but peat-based soils will probably become harder to get in the future. In general, herb soils can work quite well because they are usually fine and airy, but keep an eye on the pH according to packaging. I would add extra perlite, around 20 percent, but not too much, because otherwise it can start floating around when watering. I always fill the pots quite full, shake them a little, and water them in, because the soil will compact over time. Personally, I prefer feeding the plant later instead of heavily enriching the soil beforehand. My last attempt with autos unfortunately failed, but in the future I would use a low-nutrient, airy soil and only feed just enough to keep the plant happy. Too much is usually worse than slightly too little. In this case though, I really think it was mainly the genetics.
