Before working with coco substrate, I often had the same thing ; with autos, once they settle into their final pot, during the first 2 weeks you can feel that theyβre trying to extend their roots while still being fragile and sensitive to nutrients; as a result, the first and sometimes the second pair of true leaves show small burns.
But your seedlings in week 3 and the following week are, and will be, healthy ; the plant is now adapted enough to handle the substrate π
Think about CalMag, and if you have a root booster like Voodoo, donβt hesitate to give it a few drops π
