Brown spots, yellow and clawing

If this is your next one diary then I know your issue. You are in coco, and the substrate is extremely ph sensitive for grows. Coco Is always suppose to stay wet, it's Hydro in a potter. Your ph is 5.8 vegging, Ph is 6.1-6.2 flowering. You need to do a run off PH test, and likely a flush to correct ph. Then re add feed. Flowering npk ratio is 1-2-3. You can't overwater in coco unless you let it sit in run off.

I'd go with Krisis here. To me they look hungry too, but also not sure. One more idea to throw around. The mix of coco coir and expanded clay pebbles you're using improves drainage and aeration, which is great for root health but also means the medium dries out faster. This can lead to more frequent watering needs and potential nutrient leaching. The different ways coco and clay hold nutrients might also mean you’ll need to tweak your feeding to keep everything in balance. Best of luck Cheers, D.

My first thought was they look really hungry for bloom nutes but you said you’ve given them. Maybe she wanted more, or the medium was too dry when you gave them. Then I thought ph issue- you’re at 5.8 which I think I recall being good for veg, but should be abit higher in flower, to like 6.0/6.3. Not gonna bs you and say I’m sure here cuz I’m not. Just trying to throw ideas out there for ya.
