I think I made a big mistake. Rookie greenhouse grower. My plants are in week three of flowering. They were showing some signs of nitrogen deficiency, and slow flowering so I decided to raise my light output to 100% and top dress to spike my npk for now and with any luck get me through the end of flowering. I just played it by ear and gave 1/2 doses of fish emulsion, blood meal, worm casings, bone meal, seabird guano, and kelp blended in to the top 1” of soil. I figured the mix of quick and slow release would do well. Watered it in well. Also had the start of what I feared would be thrip issue and added nematodes and diamataceous earth. I understand runoff numbers might not be very useful for soil growing but had these numbers from a 24 hour slurry using my water this morning, just to try to get a sense of what might be happening (these numbers mean nothing to me - maybe there of value to you?)…
pH 6.5
TDS 409 ppm
Alkalinity 120 ppm
Hardness 300+ ppm
EC 858 us/cm
Now the past few days I have some plants with leaves curling up and some funny coloring on my tops. Samples below. Is it light burn? Ideas? Suggested fixes? Would it work to scoop out half my top 1” of soil and redistribute?
