Brown/Yellow specs on a couple of leaves

What can be causing this? I started in happy frog soil when they were seedlings & transplanted to a 1 gallon fabric pot with a 50/50 mix of ocean forest and happy frog w added perlite. I noticed the tips were yellow on a lot of leaves so I knew I probably had a slight nute burn (which was almost 4 weeks ago) but they seemed to push through and were growing and looking happy. All of a sudden the past week they haven’t seemed to be growing any, leaves don’t look so lively anymore I LST & defoliate leaves here & there I don’t think they are that stressed from that. Temperature & humidity in range, I have a fan blowing on them. These plants are almost 8 weeks old since popping through soil. Idk if they are where they need to be. I sprayed neem oil on them last week to control pest. So I don’t know what’s really causing the leaves to do this. I water with tap water that ranges from 40-55 ppm, I add cal mag every other watering as well. I haven’t been using any fertilizers yet except seaweed extract here & there.

I dont have very much experience, so wait for others to chime in.

I think that after 8 weeks, what ever nute charge soils had is likely depleted.

Did you spray neem on foliage with lights on? How often and how much water?

6. How often do you water and what type of water do you use?
7. What is the pH of your water?
8. What kind of fertilizer do you use and what is its NPK ratio?
9. Do you foliar feed or spray your plants with anything?
10. What kind of lights do you use and how many watts combined?
11. How close are your lights to the plants?
