It could be calcium deficiency / insect or in rare case tobacco mosaic virus (TMV)

Your PH is not in range. Or you had a massive PH swing.

Weird Spots on almost every leaf overnight? (Leaf Burn???) My plant developed these spots on the leaves basically overnight...
I was looking after them just yesterday evening and the plant was fine, however I did a mistake. The left plant got completely wet (i had to move it through the rain) and i did not dry it before the light went back on. Right plant is completely fine. No pests (thrips spimis etc.)

Noticed small brown spots kind of center of leaves, noticing some kind of chewed up deformed leaves now. From what I've read it sounds like leaf hoppers? Has anyone else had a similar experience?

Hello. When I watered 3 days ago, I saw some brown spots on the lower leaves and thought I had got some nutrient solution on the leaves but now it's on the next set too. Any idea what is going on? All 3 plants are being treated the same. Thanks Chuck.

About the 3rd, 5th and 6th picture. What's that? I always assumed it was P deficiency but I got P def on another plant and it doesn't look like that. I've had the same stuff on multiple plants. Also about the 4th picture, bottom leaves drying and white-ish between veins

Problem came back
Hey mates, sup? This week the problem is back, milder than last week but still here. I haven't added anything to the soil yet and I'm worried about it. What do you think it should be? Overfeeding, magnesium, light?

Having an issue where the leaves are spotting Brown. I’m adding cal-mag and am not having this issue on any other plants except for this one. I thought it could be from misting the air with a spray but stopped that for a while and it is still continuing.
