Leaves are curling inwards and twisting near the t...

hey @readzer1 , yeah you should be worried and that's not normal. I'm gonna start with the less bad news first. simple overwatering is leading to some issues, you can tell from the puffy leaves especially the wrinkly space in between the veins of the leaves. easy enough to correct : just make sure you're following a stricter wet dry cycle by following the "lifting method" to check if you need to water. second you want to reduce the biogrow to .5ml /L and get the bloom nutes to around 1.5ml / L , this will help the plant grow. make sure you're keeping up with micro because the plants need that in the flower stretch. the nutrient solution and the watering temperatures are much too high you want that at around 21°C otherwise you'll run into problems, just throw some ice cubes in there before you water or something. Now for the bad news, see that leaf cupping and the twisted leaves ? not good ! most likely it's due to root problems due to the overwatering and the hot solution... in soil it's hard to fix that, but not impossible. You'll want to add enzymes to every watering and add amino acids at least once a week - hopefully these will break down the rotting roots and turn them into plant food before the problem gets out of hand. Hope this helps ! 🚀
