Neem oil hasn't been terribly effective for me and if you're in flower, you don't want to be spraying OIL on your buds!... what IS effective - against thrips, spider mites, aphids, whiteflies - is Dr. Zymes Eliminator (wish I owned stock in that company!)... it's organic, NOT oil based, can be used up until harvest... Grab some and quickly because the problem is bound to get MUCH worse....
Good luck!

High bro,
This is done by thrips. You can use neem oil to spray the leaves (top and bottom) to kill those f*ckers!

If those are older leaves, my guess is magnesium deficiency. It usually gives old leaves light green or greenish-yellow dots on them. That's really all I can think of, based on the two photos you shared.
I hope this helped.

Super thin leafs at the TopThe leaves at the top are super thin, different to the others, the leaves are also darker green, I think it has some kind of problem! It looks like I overwatered it because the leaves are drooping, but that's not the case! Can anyone tell me what the problem could be?

First grow with autos, are these growing too slowly after a week?It's the start of day 7 and compared to some other posts, I worry these may be smaller than what they should be after a week. Are growing slower than they should be, and is the discoloration on the 2nd image a cause for concern?

4 times same genetic but one has hanging leavesThe top right plant´s leaves are hanging down since ~10 days. Don´t think it´s because of over-/underwatering, since I water & feed every plant the same and the others are doing great. Was it maybe too stressfull to set the LED from 160W to 240W on 35cm distance when going 12/12?

Does anyone know what’s going on here?Hey I have the following problem: A week ago, I bought some cuttings from a seller, but they turned out to be infested with thrips. To tackle this, I used yellow sticky traps and watered with nematodes. I also sprayed BAC Plant Vitality Plus on the leaves.

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?

Leaves pointing upHello,
One plant has most of its leaves pointing up. Plant look healthy otherwise. PPFD is around 650/700 and light pattern is 20/4
What could be the root cause? I read mixed answers. Some say healthy plants and or strain specific other that light stress.
Regards,
Jeanno

Weird leaf problem. Could be root?Hello community. I am currently growing three plants in the second week of outdoor flowering. I'm using the REMO Supercharger kit. One of the plants is behind the others and presented this problem on approximately 10 or 15 leaves. What could it be, a fungus or root problem?

Not sure what's causing these purple leaves and leaves drying out. Plant overall seems unhealthy near the end of flowering, any suggestions appreciateThis Dos si dos Auto has been struggling over the last couple weeks with upper leaves turning purple and drying out/breaking apart. The buds also look strange to me but that may just be from my inexperience. I'm growing in organic soil and have dry amended twice, 18 days apart.

Calcium deficiency or PH problem?Is this a calcium deficiency ? given the soil mixtures (recipes in germ. week) unlikely.
since they only get tap water, i checked the values
Ca2+ 65.6 mg/l
Mg2+ 17.3mg/l
that's an 3.8:1 ratio.
PH is 7.6, I never checked that tbh.
doesn't the soil compensate for that?
