This look like rust fungus. More ventilation, lower humidity levels, remove all infected leaves and get them out of there and burn them. Maybe do a little research. Could also just be magnesium or calcium deficiency or lock out. Cheers

Looks like spider mite infestation. Look under the leaves.

VPD related leaf issue? Brown spots, don't think its Cal related. Pls, any help would be appreicated.Brown spots on leaves, I thought it was Cal related, and tried different doses, with no success.

Calcium / PH issues? Did I take the correct steps?Am I on the right track to remedy my plant's issues? Seems like calcium deficiency to me. Soil test comes in at just under 6.5, my reservoir water going in is 7.3ph, in case its actually a lack of calcium and not the PH i've top dressed gypsum (and epsom salts).

K deficiency? Or something else?Not sure how to go about this deficiency. PH is solid at 6.5 so it’s not a ph issue. It seemed I had corrected the deficiency when it first appeared a few weeks ago, but now the brown spots seem to be spreading again. I think it might be K but not sure? Any ideas?

Nitrogen toxicity? Or calmag deficiency.Calmag added previous feeding 1 ml for 3L water.
My plants just started to preflower and added 3L water for 3 plants
3ml grow, 2ml heaven, 3ml topmaxx, 3ml bloom
That was my last schedule.
I feed with every watering 2-3 times a week. Most damaged plant is Northern Lights Auto RQ

Flush or what to do ?Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦♀️...or it is it rust?

Grayish brownish fuzz on sugar leavesTurned my northern lights plant around today and noticed this on the back of it. Yikes! Is it bud rot, pest damage, something else?
If it's bud rot I need to get rid of it ASAP because I have 6 other plants in the same grow room.

Brown spots, PH in run-off is in the high end (6.5~)I see some brown spots on my leaves. I thought it was Calcium Deficiency caused by too low PH so I gave them PH 6.5~ with 30% run-off, and run-off shows at least the same PH so I think it is not too low PH, could it be caused by something else? Maybe too high PH or light-stress?

Orange/Rust Spots on LeavesI keep getting these spots developing on my oldest mother, the MAC. She's probably rootbound, it's been about 4 months since she potted up. I need to keep her in a cup for space, will deficiency get better if I just trim about 50% roots and plant back in a cup with fresh soil?
