bl0nd3 Posted January 6, 2015 Report Share Posted January 6, 2015 Before i request opinions im sure the recent damage done to the root system may be a cause of dead foliage, however the problem started prior, and has started affecting brand new growth that is only one day old. So if any of the leaves display traits of deficency i would love your input. I have looked online and it seems the same symptoms equal the same deffeciency, yellowing, brown spots etc, so while i have been doing my research and have made a GUESS of what i think is the issue, no internet articles can be better than true experience from the community Indoor/Outdoor: IndoorGrowing Medium: PebblesWatering/Feeding Frequency: 50mls dailyNutrient Strength (PPM/EC): 112-129PH Levels: 5.5Temperature/Humidity Levels: unknown, although recently had 40 degree dayAir Flow/Fans etc.: exhaust fan, and cooling fanLighting Type: LED & CFL during night, out in sun during the dayTotal Wattage: 1150W totalGrowth Stage: VegPlants Age: 5 weeksCannabis Strain: Purple Power, White Rhino, Crystal, Ice, New York City Deisel. For the 1st one im unsure, its slightly faded small silvery patches (i took a photo of the plant leaf itself and in the photos you cant see any issues because of lighting but its just faded looking patches), i assumed it to be some kind of mite, but after looking through a microscope at 100x mag, i cant see any moving insects of any kind, just spotted silvery patches and dark dots Unknown - brown spots only seen at edges - tips dying and curling up - although on some serated edges you can see it skips. Nutrient Burn, lots of burn tips, brown remains at the tips which curl up These Leaves died after we had a 40 degree day, perhaps root damage combined with excess heat? - didnt have time to become patchy, just dried and died. root damage (as these leaves didnt last long after pot transfer) you can see the little whitish patchy spots aswell.
