Athosanswered grow question 6 years ago Check the leaves, but if you can't see bugs, I don't think you actually have them. What I can see is that you are over feeding and overwatering. There are many leaves with burnt edges.
1 gallon of water per day? that's way too much; how often are you feeding?
Let the soil dry before watering again, I use 3 gallon pots and give them half a gallon of water (2 liters) every 7 to 10 days and your feeding, 1.2 EC is too much for soil, unless you are at the peak of flowering, stay at 0,7 ot 0,8 and only 1 feeding every 7 to 10 days. I would flush the pots and not feed for at least 10 days
