Hello, recently planted my first bunch of seeds in soil. Transplanted these two from solo cup to 1 gallons. Some of their leaves are yellowing and have brown spots on them. They're curling upwards. Am I over watering? A piece of the lower leaf broke off when I touched it, was quite dry and brittle. Not sure what's going on.

I bet knowing the below 6 items would help get an answer as a few said above.

Tent temperature:
Tent humidity:
Water pH:
Water ppm:
Watering frequency:
Watering amount per watering:

what is your general method for watering? Do you soak every few days? Water every day a little bit? Several times a day?

Been trying to get the temp right. Lately at 23C/73.5F during day. RH is between 40% to 50%. Just using filtered water left overnight to dechlorinate. With these ones I transplanted then misted water near the roots before adding more soil. With two others I added soil then misted the top. The other two seem fine. I was misting the tops of the cups once every day until I realized they need to dry out some between waterings. Now its every two days. Haven’t fed them any nutes, but they’re now in a “coot’s” blend of soil. Just wanted help identifying the issue so I don’t repeat my mistake. Thanks.

try to get humidity to 55-60 with a 23C temp. I’ve used VPD to get my temp/humidity range to be optimal. give that a look to help guide the right targets for temp and humidity.

for watering, make sure you’re soaking and letting the soil dry out pretty well in between. 2 days seems reasonable tho. Before your next water, lift the pot up and see if you think it feels heavy or light. Do that every time you water to get a gage for when to water
