Overwatering ?

Thanks for replies i will easy of on watering and feed with just ph water for next 1 or 2 feeds see how they react

That is way too much water! Slow it down to maybe like 100 ml every 24 hours. It may sound wrong but what you end up doing by overwatering is drowning the roots. We give plants that are halfway through flowering like only 2 litres every third day. The gorilla glue and wedding cake plants in my west coast diary came out to only use around 2.5 litres every two days, and they were extremely big plants for my little room. Happy growing!

Hello.. Hope you are well.. Tbh they look perfectly healthy.. Early/young leaves will always curl slightly cuz they just so fragile, any excess heat/moisture is tough on them but wont hurt her.. She will grow n get huge shiny leaves.. Stay safe n gud luck.. 👍🍀

it's not ideal, but maybe not a problem too. If you are letting the coco approach dry before watering, it's likely not that. It's really difficult to overwater in coco. I have some dip in a young'en, but i am pretty sure i caused it due to light stress. So, reflect on your recent behaviour to fill in blanks. My guesstimate: That plant probably doesn't need 1L per 24 hours. Tiny plant, tiny appetite. if you've been fertilizing with 1L every day, ease up. You've now loaded up your coco with tons of nutrients that the plant hasn't even the capabilities to absorbed -- like large areas where roots don't exist, yet. I bet it clears up with 1-2 days of ph-only irrigation (not neccessarily "days" but days you irrigate) So, stick to pH-only if you've fertilized 1L/day for a few days or more. I'd only start fertilizing before 2-3 days if i see a slow down in growth or if leaves show a fade, then feed a bit less often than previously by mixing a ph-only irrigation 1/week or so... or smaller irrigation a couple times a week etc.. doesn't take much. you want to combat evaporation and lack of appetite from plant early on. Once the plant is sucking down what you give it at a pace that avoid microbial growth and toxicities, you can go back to feeding everytime or nearly everytime. I occasionally see some creeping darkness rising on my plants and dial back in bloom a tad. Less so later in life. you could try to feed some reduced amount early on, but it'd be the same thing... slowly increasing nutes concentration in substrate, but starts low enough that it won't often build up to hurt anythign, but that is suboptimal, because the plant is getting a suboptimal concentration to work with. Feed normally (by instructions unless your brand/label has cartoon graphics on it... if that's the case look into new brands that don't market to kids, because those are 9/10 trash-d%$k products. Correlated, not causal, so some may be okay) The runoff helps, but you are stil increasing concentration slowly where roots don't exist. Also, young plants sometimes just don't look perfect even if you treat them well. Likely still human error, but if so picky you can't predict, you shouldn't beat yourself up over it. take the most conservative route that involves adding the least things or preferrably adding nothing but water to further eliminate possibilities before doing anything useless and damaging in an effort to fix something but cause another problem.
