Jay, I am using 65 gallon tan smart pots and have had issues up till last couple days and now 3 of my 18 plants are drooping and not a dark green like the others are. I have been watering 55 gallons every other day so 2.5 gallons each plant. They are now about 4.5' tall, so I am not sure if I may be under watering them. What are your thoughts? Thank you in advance.
