ILGM Super Auto Mix

I am praying daily for these 1 gallon pots. The two gal pots I'm not worried about as they havent had any issues holding water. I'm sure I have root issues but praying that these 1 gal pots will be able to fill out and finish one day. 🙏 Anyone with 1 gallon in soil experience please share tips during flower. The 1 gal pots drain water almost immediately when u start to water it. I wet them until they way proper, though. They dry completely in 48 hours flat. The one gallon pots are struggling to respond. They may stand a day after watering but a day later the leaves are all sagging. I tried drying out an extra day once/feed less to see if over watering was possible but it does not seem to be my issue I don't think. Last real feed was 5ml buds and blooms by fox farm. They did well. This time I just gave water with 7.5ml of big bloom (no grow nutrient added) the 2 gal pots are doing really well on the same feed. They can go 3 days without water most times. They do not drain as drastically by any means when I water them. Is there anything I can do at this point to try to help these 1 gal girls or any tips? Will these need nutrients more often ? (Maybe not a higher dose but more doses) the coloring is good. I'm just not sure if nutrients are what they are craving or if the root system is just so bad that these may never fully develop? They were doing sooooo good and within the last week they really have slowed development and appearance. Any options for me at this point ? I have bio root from general organics but I'm not sure I can mix in organic nutes at this point since they have been in synthetics.?. Thanks for any help with this, my first ever grow. I'll never use 1 gallon pots again!!!! Stay tuned
