I think I'm coming close to the chop for these Orion's. Very nice plants that grew without to much stress. The main issue I had was time away for work made their feeding a bit off to how I would have liked.
4 litre pots are tiny and dry out so quickly I won't be going down this road again. In fact I think there's about 3l of substrate in each pot so even worse..🤣
They just get water and some beneficial liquids every third feed.
I have worked with 1-gallon pots, and I definitely feel every ounce. Those small pots require daily fertigation, sometimes two or three times a day. While I frequently travel, I know there are clear advantages and disadvantages to using larger pots. Still, your plants consistently shine. The colas are absolutely stunning!
Nice setup you have going on! Have fun with the F1 strain. I'm growing a Medusa F1 right now, but she's a bit underwhelming tbh. Still, Happy growing 🌱
