Yeah I don't have a heat mat, I didn't think it was necessary in such a small space, but I do have a soil thermometerSo I just want to chime in with a little advice, it’s coming from a good place and I’m trying to help you. Are you using a heat mat under your seedlings? Including the strawberries that haven’t popped yet?
A lot of us indoor growers forget about how much the sun plays a crucial role in seed germination by warming up the soil. Certain seeds will not germinate to the fullest potential until soil temperatures reach a certain point. One of the things that can really slow down vigorous growth of seedlings is soil temperature, which activates the microbes that are in your soil which are crucial for healthy roots. An older more established plant doesn’t rely heavily upon soil temperature as much as a new one will. Those roots are growing in the search for moisture too, so if the soil remains moist throughout the whole pot the roots won’t grow as quickly. This is one of the biggest hurdles that any new or even old grower can face, finding the happy balance for your new seedlings. I definitely have had a tough time getting this through my head over the years. I’ve really only been doing this for seven years now. And that warmer soil is going to dry out quicker and the roots will grow quicker because of this. Unfortunately autoflowers are more difficult to grow than photo period plants because they have a small window that needs to be utilized for vigorous growth, if you miss that window you end up with a six inch plant that goes into flower and you might end up with enough weed to roll a little joint. I hope that this helps put things into perspective, your plant isn’t struggling because of a lack of nutrients, it’s more than likely struggling to establish itself in the root department.

I totally get it though, my roots aren't REALLY developing.
I have my heat set at 78° , the very bottom floor reading at night is 75°
My air temps are closer to 79° with the lights on.
I REALLY appreciate the advice
