My plants are about 35 days old and seem pretty healthy overall. They were showing some signs of stunted growth and when i check the roots it seemed like it was time to transplant them from 5quart pots to 12s.

My concern is the plants lower leaves. They are turning yellow and getting a dried crispy feeling to them. I have started to lightly spray the plants with a neem oil mix to ward against a possible mite problem and am now worried the new soil i added was not fully sterilized. If there is anything in the soil causing this yellowing what can i do to prevent my plants from further harm?

The new soil mix was a blend of hummus and manure soil with some perlite and vermiculite.
