This was an experimental grow. I'm using HPCC with dry amendments and worn castings. I mixed and wet it and let it sit for about a week. I think it was around 2 cups of 4-4-4, a small bag of worm castings, and the hpcc in a 20 gallon tub. After a week it had some good growth. I mixed it again and planted the seeds. This is now about 4 weeks later. A couple leaves on 1-2 different plants have this kind of deficiency. The tips on 2 leaves are a little saggy and then there are marks on the leaves. They were just repotted from 1/4 gallon pots to these 1.5 gallon pots.

Any idea what kind of deficiency this is? I am using municipal tap water.
