Hey man that's heat stress from the high temperatures , try keeping the root zone cool by watering with water at 18/19°C and adding enzymes or another chelation agent like humic or fluvic acid to help correct the problem roots. Hope this helps ! 🚀

Sudden Leaf Yellowing – Lighting Issue or Something Else?Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.

The leaves have become glossy and yellow The last couple of days, the leaves have lifted a bit again and bent the edges, and the leaves are glossy, was it a mistake to keep the light on 24h the first week, or what do the last couple of pics look like? (I have now set the mode to 18/6) so as not to fry the plant

The leaves are wierd shaped, but growing fast Hi everyone! Please tell me, is it a consequence of leaf scorch with light, or incorrect watering, or I was very in vain in the beginning added root booster? The big question is, is it worth waiting for a potential recovery?There's nothing like it at google

Weird Curls and Holes Okaaayyy so wtf 😂 I've altered light intensity and height multiple times at this point. I've ruled out pests. I think it's either windburn, heat, light, or a combination of all 3. It's a little concerning seeing as how I think mid flower is right around the corner 😓

Too Much Light?Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Curled leaves and brown spots Please help! My Acapulco Gold suddenly showed leaf symptoms today. Shouldnt be a lock out, I always water with drain and use lower doses than the BioBizz chart recommends. Used Molasses two days ago, could that be the cause? Its the only plant that shows this signs.

Curled up leaves on day 7 I started a plant ten days ago and from the 7th day some leaves started curling upwards. I flushed the soil one day before planting the sprout and watered it again on day 9. I use the Fecida 600 lamp 16/8 day/night. Does someone know what could cause the curling of the leaves?
