Autos stunt easy from what I have heard from others. 30% perlite is great in a loamy soil, but would never be enough in clay. So it is up to you to gauge how good your soil aeration is, but it still seems suspect to me. I go with a base build of 25% potting soil, 25% coir, 25% perlite and 25% worm castings, then supplements in ratio. That base soil recipe gives a terrific combination of aeration and water retention.I would say my perlite is around 30% (its just that the coco chunks on the top are preventing you from seeing it). The two yellow leaves are the first leaves after the cotyledons. My three other plants also have the same yellow leaves. Could it be the genetics? I feed them 2.5 ml/liter of BioBizz Bio grow. in my last feed I have added. 0.5ml of Bio Bloom and a bit of Biobizz top max to my watering too. since these are autoflowers. Yes I will be transplanting it. the plant was in an even smaller container for the first week of its life too. I believe it is around 25-30 days old at this point.
You should keep it wet, always. I think its a salt build up, i heard from coco growers that when you let it dry, you get problems.How often should I water btw? I water around every 3 days
Could it also be a nutrient deficiency? Since I'm only feeding half of the recommended nutrient feed for Biobizz Bio Grow?
Lol, you called it soil in first post, please ignore my advice. Good luck!I'm not using any soil, I'm only using coco and perlite
Don’t distrupt the roots, you can transplant.Oh so autos are supposed to never be transplanted? Would it be bad if I was to transplant them into their final containers real quick? Please tell me I did not just waste 20 more days of my time cause all of my plants are literally in the same pot size and they are all the same age with 1-2 day difference. I'm going to up the fertilizer amounts as I do agree with you on how it looks as if it is starving. I'm sorry Bugeye what I mean by soil is "substrate" I'm just used to saying soil more. No I'm only using coco and perlite. I will be adding some vermicompost really soon!
