hey 👋
spots are caused either by mites or early powdery mildew
If you see tiny moving dots under the leaves or fine webs, these are mites: treat with black soap + neem oil every 3 days and increase humidity (nevertheless avoid excessive humidity!)
If the surface appears to be covered with a fine white powder, it is powdery mildew: remove the affected leaves and spray with a mixture of water and baking soda (10%)
PS: Improve ventilation to prevent recurrence 👍😕

Discolouration on fan leavesGetting a white discolouration on my fan leaves. Thought it was residue from watering with nutrients as sometimes water will land on the leaves. But it doesn’t rub off, some parts look like it’s scratched into the leaf, some parts look almost bleached. But also considering PM?Leaves. Color - Pale

Does this look like minor leaf burn, too many nutrients or something else?I believe two of the plants developed minor leaf burn. One has white streaks on the middle and outer portions of several leaves, and the other has a rust, reddish stripe parallel to the center of several leaves. I’ve attached pictures above. Thoughts are greatly appreciated.5y ago

Hello,
There are copper coloured spots on many leaves on one plant. I have tried Foliar spraying with magnesium. But it doesn’t seem to help. There is a bit of purple in the stems as well. I gave them some cal-mag, but still there. A few fungus nats. Gave nematodes 2 days ago.Week 11

Calcium issues?Is this the start of a calcium deficiency? Aside from these couple of spots the plant looks healthy, but I really don't want this to progress. I can't measure my PH for a couple of days, sadly, until I get the equip through the post to do so.Leaves. Color - Mottling

Hi Growmies, I have some drooping to the edge of leaves and discolouration. I've been watering every two to three days and live in a soft water area. Is this due to under or overwatering or is there possibly a nutrient deficiency. Thank you ✌️Week 4

Spots on yellowing leavesBrown spots on dying yellow leaves. This has happened on most of my plants after budding so thinking it may be a soil problem. My guess is boron, manganese or phosphorus as the stems on some plants are red.
It starts low and eventually ends affecting buds too so I chop.5y ago

Brown spots and yellowing leaves.I’ve just started to get these brown spots and yellowing leaves on the top leaves of one plant. Not sure what it is, potassium or calcium deficiency. Soil ph is 6.35. Water with regular nutrients at a ph of 6.5.Leaves. Curl up
