Strange leaf growth?

First of all this is not N excess or stress or mites, forget those suggestions! 2nd what 101 said, it rly looks like P excess, also u sould feed/water etc that'd be best schedule or if u like feed with every watering then half its value ppm

Looking at image , those clawing, dark green leaves on your LSD Auto are a classic sign of nitrogen toxicity. At day 30, she's likely transitioning into flower, and too much nitrogen right now can really stunt that progress. You should definitely dial back on the nutrients and give her a good flush with pH-balanced water to help reset the soil. Just keep a close eye on the new growth to make sure it comes out flatter and a lighter shade of green. Happy Growing Growmie🌱

May have more than one thing coinciding. skinny/thin blades of top leaves with chlorosis... could be too much p or k -or- too much light. If you had normal growth before, makes that less likely, but if you've increased it lately or didn't raise light with growth for a period of time, definitely a possibility for those symptoms. The clawing in could be something chewing on roots or environmental... overfeed causes claw, too. If accurate from diary, "300 tds" should not cause such a thing unless it's got some really whacky ratio of nutrients, lol. i see you do a top down irrigation occasionally... may need more of that mixed in with a little runoff or just more plain water irrigations. you are in soil, not soilless, so fertigating every time may not be the best option. Each fertigation, especially without regular runoff as you would in soiless, is adding more nutrients to the soil plus whatever amendments remain. I;m not familiar with your coast of main soi. Over-feed sounds likely, though.

Check for mites they will be crazy small underneath usually, on newer growth. Maybe HLVD 🤷 but mites are my first guess
