Leaves are turning yellow from the bottom up and I'm not sure if it's the natural death of unessery lower leaves or a nitrogen deficiency. It's not a ph problem. Thoughts?

For auto flowers you want to place your seed in the final pot size, they don't like transplants. From looking at your photos your temps / humidity seems fine as well as the light they seem to be building nodes at a healthy height and not bolting. Yellowing on the lower leaves would suggest that it is a mobile nutrient issue, if nutrients are your issue. Mobile nutrients are Nitrogen / Phosphorus / Potassium / Calcium and Magnesium The other types are Immobile nutrients which show on newer top growth leaves. Immobile nutrients are Manganese / Iron and Sulfur there are more these are just examples . From looking at the leaves it would suggest a very mild potassium or nitrogen deficiency but at this stage i wouldn't worry to much as its mild and you dont want to over feed them. Make sure you are not over watering or under watering as this can cause problems as well that look like other issues. Good luck and happy growing 😊

Do you see roots at the bottom? They may be just getting too big for those pots... I've heard once the leaves reach the outside of the pot you should transfer.

I have ph strips and if they're to be trusted the ph is 6 ish. I'm certain they need repotting but I'm trying to get that third set of leaves in before I move them to their new pots

too early for it to be shedding leaves. Yellow creeping up is a sign of nitro deficiency for sure... if your behaviour before this point is relevant, you need to consider it. Have you fed regularly? is the pH correct? if you are certain of these things, go ahead and fertilize. it likely needs it. A plant will get rid of a lower, light-deprived leaf, but not on any plant this small. If fed slightly better, even that shouldn't happen except in later bloom. if it does, it's a minor issue... more of a hint to start feeding again or a tad more.

how high is your ph exactly? and an ec of 1.0 I find a bit high for this stadium :-)

Возможно вашим растениям не хватает света, опустите лампу ниже. Так же это может быть из-за кислотности вашей воды. А вообще автоцветущие растения нельзя так долго держать в маленьком горшке
