Normal for cotyledon leaves to wither during preflower?

G14 auto just hit preflower, moving towards flowering. (Pic below.) This is 29 days after seedling emerged.

Bottom cotyledon leaves are drying up a bit and some of the very bottom fan leaves are lighter green than my ones up top-is this normal due to plant pushing nutrients and water up top? Also is it too early to get some tiger bloom going or do I wait for actual buds?

Im in FFHF soil. This is my first grow so any feedback appreciated. It seems healthy so far?

Had to google what cotyledon meant, the very first little round leaves... and yes. That's normal.

Hey I taught something to someone today. Time to eat pizza and rest on my laurels.

Thanks for the assist.

the cotyledons have no use after a plants baby phase. its just used to get the initial light before the first set of leaves come out.

Thanks, that was my guess-that they’re primarily embryonic. Is it safe to assume some lightening of the lower leaves that are getting shades out is a result of less light/more nutrients heading up to the flowers?

the leaf color change on the bottom has to do with mobile nutrients. the 4 mobile nutes are npks everything else is immobile. if the lower ones are a bit more yellow its just from less n in your plant. a small shade isnt anything to worry about. these plants turned out great and look how yellow the fan leaves were at the bottoms
