What's your humidity and umols? The two lower leaves could just be light burn, the first 2 serrated leaves cant handle much light. High humidity and over watering can cause leaf curl like that.

pH most probably cost magnesium ( tigery stripes ) with calcium ( pale colour and rusty spots) Let them always dry out, measure pH, feed light calmag few times like 0.5 ml/l max and on third watering can return back to normal nute schedule , but only if they drink regularly ... pH and watering regime is half of harvest success ... All the Best !

ppm out 1000 is your indicator. To much feed and salt buildup. Lower up on the nutrients. should aim for 200 as a seedling then increase by 100 a week if it can take it. capping off around 600-800 in veg for photoperiod strains. Autoflowers you need less. Use this link for auto feeding guidelines. https://www.autoflower.net/forums/threads/med-man-method-feeding-chart-ppm-ec.47856/ Good Luck!

Why you feeding so much? I’d tone that down for sure.. Did you buffer coco? It will leech your mag and calcium and other micros if not buffered

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.

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?

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.

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.

Are CBD-Strains less nutrient-hungry?Hey Guys, i experienced that these strains like a lower EC/TDS. Every time i went over 1.2 EC (600ppm TDS) they showed signs of over-nutrition, like very dark green leaves and reddish brown leavetips. What are your thoughts on this? Are CBD-Strains less hungry on nutrients?
