Note humidity was high i had turned off fans ,thought was too much breeze
I’m dealing with the same thing so clearly I’m not the expert, others will have more thoughts. For my two bitcoin, at 84% the humidity is high based on the VPD chart that goes around. Also, do you use the photone app to determine the intensity of the lights at the leaves? The PPFD and DLI may inform whether you have a little too much light. The app is free and the charts are widely available. Sticking to those helps a lot.

Whoops, sorry - I’d also keep the fans on.

Overwatering is the numero uno problem encountered with seedlings. This isn’t a huge issue with photoperiods as they have time to recover and rebuild their root structure before going into flower. Autoflowers, however, have very little recovery window, since they start to flower when they want. If they go into flower while they are experiencing transplant shock, recovering from overwatering, or something that puts them in recovery mode, while they’re still small, then you’re likely going to end up a small plant.
Also, as mentioned, the photone app, or a decent light meter, are good tools to have in the belt. At 18", and 75% your plant probably wants some more light.
Your humidity ahould be down in the 40’s, low 50%'s while flowering. That is a sure fire way to catch mold. It isn’t so bad for a seedling. In veg they prefer high 50’s and low 60%'s. But during flowering, i try to stay between 40-50% rh.
Lastly, if you’re using the green probe meter for anything other than soil moisture, toss it. They aren’t even much good for that either. The “lift test” is best for watering practices. If the bag is light, water. Your pant shouldn’t need more than a cup or 2 of water every 3 or so days. At that size. And water closer the the sides of the bag, away from the stem.
Hope this helps. Good luck and happy growing!!!
