The photos are of my Mother Plant, she is a Bannana Kush, Temps are warm and humidity is high. Does not resemble powdery mildew, at least none I have seen before. Any suggestions to help me identify this problem would be sweet.
Ph is at 6
nutes are GH Grow, and micro at aa ppm of 90
using Distilled water
Nute burn. Flush with sugar/mollasses. What soil you using? Miracle kill?
Everything written on here is a figment of my over-active imagination caused by mental health problems due to low THC levels in my brain. All pictures are posted by a mysterious stranger who hacks into my PC when I'm not looking. I'm not even sure I am real.
Looks like a combo of a few things. Definitely some nute burn. Flush em like folks have said, with a very mild ph balanced solution. Also, 86 is quite hot. Anything over 27 and it can stress the plant quite a bit, some strains more than others. Lastly, at 8600K, your light doesn't provide a spectrum that is easily utilized by your plants. Get a 2700K lamp as well. The blue from your 8600 will keep internode spacing down, and the 2700 will better mimic actual sunlight, and will be ESSENTIAL during flowering with it's red spectrum. Also keep in mind, there are alot of excellent small hid lights available that will be more efficient, although I have a soft spot for flouros, they disperse their heat more evenly. An hid is advised for flowering though...
Keep creating.
Oh, and no that is not "kush", dipsh*t.
I would disagree that this is nute burn.
IMO its the opposite, I see both Mg and K deficiencies by the curling and necrosis of leaf margins. 86 is high, and the proximity of the cfl's doesn't help the temp. The high temps and lack of K adds to the tissue death on the margins due to the increased rate of transpiration, research vapor pressure deficit, it compounds the K problem even further
A decent sized mother plant in clay pellets with a 90ppm feeding dosage makes a convincing case of deficiency, just my 2 cents.
Give it a good flush + feeding.
As for the crustage, I've seen excess Ca as a culplrit before but not like your pics show.
