what does it appear the problem is? she is wrinkly...

hey there HM , you're still overwatering my friend, this you can see from the puffy space between the veins of the leafs, it sounds silly but it's the most common problem. Try the lifting pot method to never overwater again : www.youtube.com/watch for the wilting you're right, but youve caught it early so you have a chance still. What i can see is that you're on a heavy lighting regime but you're not adding cal mag which is leading to yellowing at the serrated edges of the leafs, with such a heavy light regimen you need more magnesium. You're also adding fish miix but not measuring your pH, fish mix raises pH by quite a lot which can cause uptake issues. i would try cutting back on it until you can measure pH. i use pH strips like in school, tthey're cheap they work and dont need any calibration. Hope this helps ! 🚀

From the looks of the photo, she's still suffering from the overwatering the leaves look full of water and are wilting. Hopefully, I answered your question and remember Happy Growing and Free your mind one puff at a time.

and the fitting theme is nutrients------ be sure the medium is humid/ well drained befdore you add nutrients.....this way you avoid strange " islands" where is nutrient or not.... the nutes spread better in a humid medium
