Setup: Ebb & Grow bucket system w/ 55 gallon reservoir GH Rapid Rooter plugs in Hydroton (1) 1000W MH for veg temps were fluctuating between 68-83 but now stable at 73-77 reservoir temp is a stable 68 p.h Is between 5.5 - 6.5 ( it wants to steadily rise every day to 6.2 +) ppm are at 500ish with Technaflora's BC line following the Recipe for Success From the start 1 plant (the most mature) had leaves curling up. I thought it was a heat issue but I stabilized temps and it still progressed and spread to 4 or 5 others. 1 plant is showing sort of 'wet scarring' and deterioration on a leaf. 2 plants are showing spotting that started as a rust color and has turned brown It started on lower growth halted and has just resumed on newer growth. I attributed all of this to nutrient deficiencies and upped my solution to it's current 500 pm and all seemed fine. Now the plants are wilting at night and taking all day to recover if at all. I thought maybe it was over watering so I cut the system off and let them be. No changes for the worse or better. You can track the progression in my journal (link in sig) Thanks in advance.
