I pollinated some females last grow and got a few seeds in attempts to create a new hybrid. The seeds germinate in a bag with wet paper towel then i throw them in a pot of happy frog. They grow a few leaves then stop growing completely and turn a lighter green. I've had multiple successful grows in the same environment so confused why things aren't working. What's the issue and how can I fix it? I water every 2 or 3 days depending on weight. No fertilizer. Using spider farmer led. Temp is 72 and humidity is a measly 22%. No tent just an open space. Tent got up to 98 so had to remove them. Lots of gnats which happy frog denied being responsible for but its winter and these are the only plants I have. Tried to top dress with perlite and sand to prevent more eggs. Thanks for you time and reading. Have a marvelous day.

There probably are several issues. The question I'm asking myself is, where to start? They look like they're starving.

I think I would pull them out of their pots and remove the sand and perlite from the top. It's possible to remove all the soil and replant, but that might not be necessary. The lower stem can be put in soil and root, so I might remove some of the soil and repot them deeper in the new soil and introduce some water in nutrients. I've recently been using Root Fertilizer from Bloom City for my young plants with success. It is an organic root stimulant that includes microbes.

I water every 2 or 3 days depending on weight. No fertilizer. Using spider farmer led.
I'd guess the soil is too wet.

Temp is 72 and humidity is a measly 22%. No tent just an open space. Tent got up to 98 so had to remove them.
The humidity is way too low. Young plants should be in 55% RH (or higher) --a VPD of 0.8 to 1.0.

Lots of gnats which happy frog denied being responsible for but its winter and these are the only plants I have. Tried to top dress with perlite and sand to prevent more eggs.
The best way to control gnats is to let the top layer of the soil dry--about an inch. That's where the larvae live. If the soil is dry, they die.

There are other methods, but those plants are vulnerable due to stress, so be careful.

Many growers blame Fox Farm soil, but it's not really the soil's fault. Fungus gnats like soil with wood in it. Wood is good for soil because it composts slowly and microbes in the soil like it, thus organic growers tend to like it. Wood also affects soil moisture, but that's another thing.

Welcome. Sorry to see your having problems.
Agree with LoveGrowingIt.
IDK but watering every 2 or 3 days seems too often. Need a dry back period. Every grow is different. How high is the light and what is intensity. Likely should be around 30" and 30% to start.
Gnats should be expected when you get good organic soil. Complaining about them is like complaining water is wet. Be prepared with fly paper. I make little cardboard cutouts, put section of flypaper on each side, lay on top of cup beside stem. Gnats fly up off soil and get stuck. If you water cycle by getting the whole pot wet and then letting it dry back the larva will tend to die in the dry soil at the top while the roots grow deep to find moisture, so win win. Keeping it wet all the time is a no no.

Over watering, need to feed, look up the NPK of Happy Frog,,, weak as water. And 72f and 22% RH is low for any stage of grow unless there landstrain indicas. Plus if this is your first cross/breeding of a strain they can be massively unstable. Good Luck!

ya need to kill the bugs laying the eggs,ive had root aphids and plants looked similar.Did a root drench and never looked back.the yellow stickys dont nstop the source. Its frustrating shit.

Thank you and everyone for responding. The genetic statement makes a lot of sense as well as the humidity. I mixed a dash of worm casting, liquid silica, and fish shit together then watered lightly. Also drilled some holes in a sterlite container and covered them. Humidity is 65% and its 78 Fahrenheit. I gave up on the first batch only to see new growth as they sat in the cold so brought them back in and now one is preflowering. I stated these in November! So its been stressful finding out the hard way but thank you all again for the shared knowledge. I have sticky traps sand and hydrogen peroxide for gnats but still no luck. I'll keep you all posted in the coming weeks.

You need to get that humidity up somehow, you have very bad VPD your plants are overtranspirating. If you cant get the humidity higher lower the temperatures, thats why theyre droopy. As for the rest people already mentioned it.
This is your VPD right now, play around with the parameters to get it to a the zone you need for early veg or as close as possible, at least outside of the danger zone.

change your pots , those pots are rubbish, they are flat on the bottom with little drainage, they hold onto too much water and all that sand isnt allowing much air to get through to the soil .
my first 2-3 grows went like that and it was overwatering , as well as using lemon juice to ph my water down, which kills all the microbacteria

Ok so I guess I'm aiming for .6 kpa and I need to get my humidity up to 75. I've noticed the same soil I have in bigger pots I'm going transplant in is extremely hydrophobic. Tried to water it and it just pooled out the sides. This has been an eye opener on optimal settings. I've never had a problem like this growing until now so it kind of puts you in check on standards. The little pots are different than what I've used before so they may have a point on that as well.

Dry soil will always do that. When your soil is dry and you have textile pots you need to be patient. Once you get the soil wet it should be way easier to water next time. Even then if you water too quickly dry pockets inside the pot might make your water slide to the sides. This is completely normal is not that your soil is hydrophobic its just that water slides on dry soil, needs to soak up before it can let the water pass.

Oh definetely, I was just talking about the droopyness, you can have more problems going like other people said. Im just pointing out what I know for sure but that might not be the full picture. I just know that your VPD is or was very bad and that causes droopyness if its too high because of overtranspiration.

Going back to watering dry soil. Be patient, happy frog is a peat based soil it retains a fair ammount of moisture it was just too dry, at least on the top. Thats why soil usually comes with a minium ammount of moisture, so you can water properly when you prepare it and so it doesnt create a lot of dust when youre pouring it. Since you prepared the pots in advance it probably lost its initial moisture and thats why it was hard to water it the first time.
