Without pictures it's hard to tell. If you re-pot, then the plants have at least that much more food to eat and there shouldn't be any other consequences. In fact, I doubt it could hurt when we're talking about this plant.

Do you

Low humidity can cause the yellowing and the drooping. Are these leaves getting any light? I lose leaves low down all the time that start with yellowing due to there being a lack of light down low

we need pics badly I’m klukking to see these girls. I have some seedlings that I repotted today been in half the size pot as you with light mix soil (weak soil) and barely any nutrients for around six weeks maybe more and I had no yellowing at all. I recently had a spell of low humidity down to sometimes 18% and my plants were fucked exactly the same as my cousins who was also experiencing low humidity drooping yellow leaves at first then brown spots and crisping off. They went dormant didn’t grow at all until the humidity levels raised, soon as humidity went up leaves started greening up and new growth started.

Whatever you have done you probably damaged your plants the roots in dirt , not the roots at the edge of the pot. Your plant wants to grow new roots, roots grow down and out and the roots you do have are probably at the edges of the pot, so repoting is the quickest way to recover. If you don't' repot, the plant will recover, if you clean up your act and stop doing whatever it is that the plants don't like, but it will take much longer because it will have to start growing new roots from further up the rootstalk which is something pot plants don't like to do

Where I live low even single digit RH is common especially this time of year for many many years (before internet) I had no idea they preferred higher RH as seedlings an during veg an grew some mighty fine plants, that being said I do see slightly happier seedlings these days but if all other plant needs are being met low RH has never been an issue for me I do grow sativa and sativa dominated strains... Without photos we are unable to help..

Epsome salt will supply your plant with magnesium for photosynthesis and sulfur for water regulation. 7.0 ph h20 will stop any issues with acidity/alkalinity

Good info, thank you. I've been watering with about 8-10 ounces every other day for weeks but the yellowing is new. Pots are light and a moisture meter shows dry to the bottom of the pot after 2 days. Let me know if these pictures are good enough. Just got a lux meter, 27000 at the top of the plant.

IMO, it's time to re-pot. While they're still an OK size for their containers, it's possible most of the needed nutrients are gone from the soil after six weeks. Putting them in a bigger container will do three things. 1, give them brand new soil to enjoy. 2, make adding fertilizer safer. The more medium you have, the less chance of overfeeding. 3, like the fertilizer the more medium you have to hold water the less chance you'll over/under do it.

I don't see any major problems. Before I took drastic steps I would replant them.

You want at least 40000 lux. so add light or lower the light, keep the plant above 70 degrees day and night. repot aND keep letting those plants have a dry cycle

That is low humidity without a doubt some strains are more resistant to it and are less affected by It, it looks similar to overwatering. Those yellowing leaves are nothing to worry about, they are down low and your plant is sucking energy out of them to continue growing up top I get loads of them when I have big bush plants. Your girls don’t look underfed at all by the way. I can see yellow tips on leaves usually a sign of too much nutes. Evan soil can do this on its own without you adding nutes. That’s what I think is going on here
