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.

No tip bladesA few of my new growth leaves have grown without tips on the middle blades. I thought it may have been a wind issue so I turned one of my fans off. It’s also gotten cooler recently so that may have played a part. Has anyone dealt with this issue before?

Dying leaves?? - Brown spots lower leavesThe cotyledon leaves are dying on one of my plants, but these brown spots have spread across lower leaves that were damaged by the shell. Is this natural or is it a problem I’m unaware of? Not over-watering and pH is fine. Brown spots have appeared on tips of next leaves up now!

Do these random spots mean nutrient burn/deficiency, or is this normal?I have been feeding my plants 1/2 strength FF once weekly since week 3. The plants seem to be doing well. One has twisted leaves but seems healthy. But the plants are displaying random spots of yellowing. Is this normal or indicative of some kind of nute issue?

Yellow leaf septoria?Hi, I think some of my plants have yellow leaf septoria. How best to treat this? Should I consider removing leaves, plants or maybe starting again.
It might of been due to my constant misting to maintain a high humidity at the start or I was also thinking fungus gnats

C02 exhaust bagHi. I wanted to know if adding a CO2 exhaust bag in a small grow tent (60x60cm) is effective for overall growth? I'm European and most off my pairs said it was useless but the topics dated from 2010s and I couldn't find current definitive argument so... here I am.

leaves dry and curling upGelato canopy leaves continue to dry and canoeing up. I've backed off the lights, changed the air circulation, and gave only water in the last week, but the situation is just getting worse. Canopy buds are not growing and trichomes production is much higher in the lower branches

Phosphorus deficiency?I think this is a phosphorus deficiency. I thought it was because I slightly overwatered the plant. I gave the plant 1.5l water without nutrients then waited 4 days. Then 1.5l water with nutrients will also wait 4 days. The problem seems to get worse. Anyone any advise?
