A little background info...
Seeds or clones, source? clones
How old are the plants? week 4 bloom
How big are the plants? 20"
Lighting wattage & distance? 1000w @ 2.5 ft
Soil ingredients or hydro system? hydro
Container size? ebb & flow table
Watering frequency? How do you judge this? 1 hr 4 times per day
Fertilizers used and how often? SuperBloom A/B
How do you ventilate the space? Active exhaust
Other details? Include photos if possible.
I have included 3 pictures: one showing early signs, and two showing later signs. Veins of affected leaves and entire plants red (not due to strain, but unhappiness). Problem begins with interveinal chlorosis on older fan leaves. Then these leaves develop necrotic regions, but generally not on leaf margins (but from center of leaf).
Plants suffering from what appears to be mixture(?) of deficiencies. Mg most likely as best I can tell, but uncertain. Must stem from problems in root zone. Roots rotting in tray, covered in dark brown slime. Could this be due to cold res temps? No res thermometer, but it's pretty cold in the basement (concrete floor, but res sitting on piece of insulation.
Atmosphere not as constant as in times past. New room; not all kinks worked out yet. DIF (difference in night and day temps) is around 20F. Gets down to low 60's F at night.
Grew same strain a couple of months ago with no problems. Any assistance greatly appreciated.
