Too early to call. Could be a thrip or gnat problem, could just be where the leaf burned from a droplet evaporating, could be the start of a nute problem, it could be nothing.
Keep an eye on it and check the leaves for tiny bugs. Especially the undersides. Post again if it spreads.

It could be a thrips signs, you can solve It by putting neem oil and water at the leaves and they will no longer eat your leaves. Your leaves are curling on their serrated part. Put your light some cm away from the plants.

Thinning leavesI'm also noticing my leaves are thinning out badly and clawing in some places. The RH has been down to like 17-18% but I was led to understand low RH is the goal during flower. For now I've put a very gentle humidifier in. RH now sits at ~30% is this okay?Leaves. Other

Spider mites in floweringSpidermites detected in flowering. Still no webs forming on buds but there is small damage on leaves. I have neem oil but don't wanna ruin my buds with bad smell and heard neem is toxic to humans. Rosemary essential oil maybe?
I will be washing the buds at harvest.Week 9

In addition to former questionI am growing on Cocos mix. I add Calmag 1 ml/L once a week. I do not measure PH (never did) because of organic nutrients. no runoff, I like to keep my plants a bit dry (about 150 mBar on Tensio) for better rooting. So just more Sugar Royal? Daily 1ml/L instead of 2ml/L weekly?Week 4

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on AutoWeek 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition?
I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1ECLeaves. Tips - Burnt

Been struggling with leaf issues for weeks. Initially thought lockout due to N toxicity. Plants improved after flush in Week 7 but then promptly started worsening a few days ago. Is this a continuation of a lockout issue? Would you feed? Flush? Advice is welcome! 🙏Week 8
