Not sure what's going on but I have brown spots on the lower leaves. Initially thought it was from spraying water on the plant but I think it was an infestation, therefore, I ran and got some neem oil and applied as directed. Shortly after this, the plant began to droop and has not lifted. Any ideas? Should I just restart?
That looks more like a calcium deficiency :/ Cal mag supplement at 3ml - 5ml per gallon and see how that works out for you. What is the initial ppm of the water you are using??
