Douse anyone know why the bottom leaves are droopy but all new growth is fine. Seed starter organic soil. NO nutrition yet only watering when top inch is dry.I I’m trying to low the humidity to 65% it was at like 75-80% first two weeks.376A997C-460E-4EB1-97FC-12791D0DF06E.jpeg

Looks like a water or moisture issue. Not enough air exchange in the space? No drainage in solo cups? Too humid-VPD issues causing cal mag deficiency?

I have a ac infinity on automated the humidity was set to 85 in the early stages and I found out I had to much calcium in the water I was putting in my humidifier could that be it?

No I recently actually dimmed my light earlier today cuz I thought the same thing
If they keep getting more and more yellow, it must be because of the light, temperatures or air movement. Im not too sure how much humidity would affect them at this stage of their growth, but if they're already going yellow, something is definitely wrong. My tap water is high in calcium as well, never had an issue, the plants seem to love it, actually.

The soil he is using looks like its super high in bio acitivity.... I would doubt 1 or two slight waterings would be able to change the actual PH of his soil in those small pots?

Edit: With a soil with no nutes, would seedlings his stage be going yellow yet?
