Sorry for the late update. First off thanks to all who have replied. They were definitely on the dryer side. I am now watering 3-4 liters and likely every 3-4 days. The light is now at 500 ppfd and they are in 7 gallon fabrics. I fed them with Gaia green 444 (2 tbsp) and 284 (5 tbsp). They are doing much better. I'm new to autos but run 2 tents of photos with no issues. These autos seems to be very hard to keep happy compared to my photos. These are not the best genetics either I'm afraid. Once again appreciate all your time and input. Take care and have a great day!
