Growing 4 plants from seed. 2 autoflowers in hydroponic setup and 2 photoperiods in soil. No nutrients given to the soil plants. They are growing under 2x30w blurples until the x 100w LEDs are available at round week 5. Don't know exact strains, because the seeds were mixed up. But the autos are either Bruce Banner from Silver Leaf or Strawberry Banana from 420 Fast Buds. The photos could be either AF KUSH, GELATO 33, GUSHERS, CALI GLUE, RUNTZ, GELATO 45, CALIFORNIA HEADBAND or GORILLA SKITTLEZ.
Got some gnats flying around. Going to alternate Cannacure, Neem, BioProtect foliar feed, implement diatomatecous earth as top layer.
Got pest in my grow and almost killed my plants with a heavy duty dollar application with bicarbonate of soda. I also used neem, chilli and the rest of the kitchen sink..
Can anyone confirm wether or not I have powdery mildew? I had a suspicion and did a h202 foliar hoping to catch it in the bud... PS: the brown stuff on some of the leaves is cinnamon powder..
in your very first photo is looks as if the light reflecting off the bent tip of the leave is white and powdery but I think that's the light.
I do agree with the other your looking like a excess of N is causing all the leaves to be real dark. Will want to get that in check before it causes some other issues.
Good Luck!
I don't see any, but you do need less nitrogen and more potassium in your feed. Flowering NPK ratio is 1-2-3. Brown straight tips on leaves is potassium deficiency sign. The shade if green says how much nitrogen is in the plant. Try to keep you rh between 40 to 50. Above 70 rh and you will have issues for sure.
I'm not seeing any powdery mildew, thankfully... I'm seeing what might be some insect damage (maybe spider mites, maybe thrips) .. I would get some Dr. Zymes Eliminator or some Spinosad and if you see an increase in the small white markings, get to spraying with either one of these - they're both organic (although Canada does not consider Spinosad to be organic for some reason) and can be sprayed all the way through to harvest if need be... If you need to use either one, always spray just before lights out..
Good luck!
