Original Blueberry Regular Seeds

Only a coue pics upthis week. Nothing new happening. Slow growing. All still alive and doing well. Next week will transplant any that need it. 2 seem to have a nice burn which seems to be from the soil bit I'm not sure why only a couple are affected. I use the same dirt for all my grows and only some ever get it. I asked it as a question but the answer was its my dirt. If anyone else has any ideas as to why ( if it was the dirt ALL my plants should be affected i would think) a second opinion is welcome. Anyways I think that's about it this week. Cheers
