That looks like spider mites. Check the undersides of leaves for them.

Help, what are those weird yellow spots in late veg?
Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid. Checked the whole bud, but no insects. My other ideas are mold or stress from the light?

Yellow bottom leaves/brown spots on bottom leaves
Hi guys, So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her? Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else? Besides this, the general condition of the plant is good. Tx!

Spots on leaves
I'm still dealing with some spots that seem like cal-mag lock-out/deficiency but my PH is at 6.2-6.5. I think the light was too powerful I moved it up from about 16" to 18". I hope to have a lux meter soon to confirm any light stress issue. Still look like PH fluctuation?

From previous post just some more infon on what I feed and how, on a 12
So I use 5 ML per gallon of fox farm Grow Big Liquid Plant Food, And 5 ML Per Gallon Of Fox Farm Buds And Blooms Fertilizer. I'm barely staring to Introduce Cal-Mag so I don't think the Cal-Mag is causing the issue, I water every 2-3 Days. Temp is Right Around 80 during the day 7

Hi all. I was fighting with mites, but last 3 weeks they are gone. There is yellow spots (boundless) scattered irregularly all over the leaf. Most often these spots are at the edges of the leaf and at the tips. I feed them only half doses regarding to nutrient schedule. thanks!

Please help! What am I doing wrong? I’m a first time grower
My leaves were burning and now I know that I am burning it with nutrients cause my soil already got nutrients. I’m only using water now but now they are turning yellow and the big leaves have spotting. What’s the problem now and how can I fix it?

How do I achieve the dark green leaves wedding cake wants? (More nitrogen?)
My plants are looking overall healthy but are not as dark green as I’ve seen most plants at this stage of growth, or like my plant on the bottom right of the canopy. I am feeding/foliar treating the same amounts to all plants. wondering what to do or should I just chill out?
