Hello, For the second year in a row I've run into stunted seedlings. I suspect there is something amiss with my seed starting mix (low pH?). The issue: Seedlings of all types (peppers, brassicas, onions) germinate just fine. Cotyledons come out and grow to a normal size. But then...stasis...true leaves don't emerge within even 2+ weeks after the cotyledons are fully formed. In fact, even the cotyledons may yellow or fall off before substantial true leaves emerge. I've been doing indoor seed starting for 5 years and the first 3 years this never occurred, cotyledons would make way for large, healthy true leaves 7-14 days after cotyledon formation. I start seedlings in 6 or 4 cell plastic trays. The seedlings aren't leggy, as they receive plenty of light, with some grow lights probably 4 inches above seedlings. The seedlings are nice and green. I don't overwater. I typically let the top layer of mix dry out before watering. The seedlings don't wilt or look stressed before I water. Last year, I used a 1:1:1 mixture of peat moss, vermiculite, and perlite. This year I used a mix of standard potting soil (some soluble nitrogen, but very little) and perlite. Same issue. I live in Minneapolis and water with unfiltered city water, but I watered with unfiltered city water before and the seedlings grew just fine. I wash my seedling containers each year. I fixed everything last year by transferring into a dedicated seed starting mix from Miracle Gro that I mixed with a little bit of perlite. As soon as I moved to that mix everything started recovering very quickly. True leaves started forming and I was able to transplant on a normal schedule. I'm going to do the same thing this weekend. Buy some dedicated seed starting mix and go through the tedious process of carefully removing seedlings and transplanting them and their delicate roots in a new container with new soil. BUT, I don't want to keep dealing with all of this extra work and turmoil from static seedlings! Do you have any thoughts? I was thinking it could be a pH issue. What should I do next year so that this doesn't happen again?? Thank you for your time, Dustin
