This is my first grow, 4 Runtz seeds from ILGM female photos. this is the morning of day 7 from sprout in Fox Farm Happy Frog. Brown spots appeared yesterday (day 6) and seem to have progressed. This morning the leaves started to warp different directions, one of them facing upwards and other 3 drooping downwards. The only thing I can imagine is wrong is that they have been overwatered, I typically water twice a day with just about 30 ml to each solo cup. Any help would be much appreciated.

stop watering like that. water enough to make sure all the medium is wet and than let it dry out before watering again..

I figured i would wait a full two days to see if they liven up, but is there anything else I should do? Would it be better to let them do their thing or is it too much stress that I should plan on starting another batch of seeds

Do you have plenty of drainage holes in your cups? Something like this:

Solo cup holes

I did 6 holes for each cup, and only let drainage when i watered the soil before planting the germinated seeds. the first few days i used a spray bottle until day 5 i started using a dropper. I got the ph very close to 6 for each water, but did water twice a day for two days

Like @GNick55 said, I think your primary issue is over-watering. Note that over-watering is NOT giving too much water at once. It's watering too often. "Correct" watering frequency depends on your media. Happy Frog, which I've run many times, is hypoxic at field saturation. That's a fancy way of saying that it holds onto water so long that the roots don't get enough air. The solution is to water to run-off, and then let the pots/cups dry back until they're very light in weight. That might take a week or longer with new seedlings in solos.

Ok, thanks for the help! To be clear, I should water them now until some comes out of the drainage holes and then let them sit until the medium is dry? Just don’t want to get too excited and do it prematurely.

I'd let them get light before watering.

Thanks for the help, I’ll update this thread maybe tomorrow morning if anything has changed. It’ll be night from 12-4 today, unless you would recommend leaving the light on 24 hours. Either way, thank you for the advice.

I run seedlings for the first month under 24 hours of T5, but other schedules work well, too.
