DWC, 7.5 lpm air
53 days into flower
Temp: 65-80
Lights: 12/12 1000 W HPS
PH: between 5.8 and 6.2
PPM: starts at 1200 on sunday and drops to 700 or so by the following sunday. (200 ppm is the water)
Water: Tap water, 200 ppm (included in ppm above)
Nutes:
Pure Blend Pro Bloom - 1 1/2 tbsp / gallon
Liquid Karma - 1 1/2 tsp / gallon
This started showing up a week and half ago I think it may be a fungus.
I thought nute burn initially and backed off the nutes from full to 3/4 dose and it did not seem to make a difference.
I dont think its nute burn because the spots are also on the leaf interior and there are healthy and bad leaves all over the plant.
I see no signs of bugs, on the bottom of the plant a lot of leaves turned yellow and started dying.
The stems seem awful dark to me but cutting them in half they still look healthy.
I think I have 2-3 weeks before chopping so I need to know what everyone thinks it is and what I can do given the amount of time left. I picked up some serenade garden disease control from the local hydro shop, the guy there told me it was safe to use even this late in the bloom. (Active ingredient QST 713 strain of Bacillus subtillis)
Should I just chop them down now since I probably wont grow any new leaves at this stage? Some yield is better than zero if its a fungus or something.
