I wouldn't worry about those 1st set of leaves. They generally don't stay healthy for long.

What is this rust discoloration on leaves, and how can I stop it?
Does anyone happen to know what is causing this rust colored discoloration on fan leaves? It starts on bottom leaves, and moves up. Also seeing yellowing on leaves, and not sure if its pest issue, light issue, deficiency, or watering concern. Super nervous plants are dying🙁

Calmag Deficiency? Yellow Spots
Last res change I saw some yellow/brown spots on the fan leaves up where the main cola was getting too close to the light. Is this a calmag deficiency or light too close? I moved the light up to the top of my tent with zip ties and got back several needed inches. See pics.

Mites, root rot, or light intensity
Does anyone know about tiny yellow dots on new developing leaves are a sign of in early veg? Im growing in RDWC so I didn’t think mites would be an issue. I did notice one relatively brownish root as well, but the rest were all white and healthy. what should I do?

Weird leaf
It seems one of my leaves has become very oddly curled up. It has very slight brown spots with a strangely curled up tip. As seen on Week3-day19. Can anyone identify some sort of problem like excess or deficiency of nutrients?
