what's wrong

looks like this plant is way too cold

If i misunderstood question n ur on bout ec ph etc.. Just drop ur flush water to ph.6 n it shud drain lower ph levels.. Ppm 250 means shes not got lots of food stored around root system so alls cool tbh.. 👍🍀

Hello.. Hope you are well.. On the 1st pic i can see the big fan leaf at top pointing towards us has a nit of moisture on the middle leaf.. This is wer the other leaf has been sat on top and shes sweating a bit.. Just put a fan on her to keep fresh air moving her leaves.. Not blowing crazy tho.. Just a nice gentle breeze will do.. U cud try raising her feed very very slightly as she clearly goin into flower i wud use just ur base nutes for blooming as this will av trace elements of nitrogen so shud give her a bit of shinny colour aswell.. Apart from that she lookin great.. Nice big fan leaf n potential for fat nugs.. Stay safe n gud luck with her.. 👍🍀

Hi there, what's your growing medium? Soil i guess? (you don't have a diary, so there's no way of knowing any details) the difference of PH of 0.1 i don't really see an issue with, that can be neglected.. You state the rinse-off has a ppm of 250 (not sure which ppm scale, there are multiple, but i will assume you mean the hanna) means EC of 0.5, which is basically around the mark that soil should be fertilised with.. (see: https://www.mandalaseeds.com/Guides/Fertilizing-Smart-Guide). Obviously if you start flushing you are doing this to remove excess nutrients that are stored within the soil, so you will see a reading in the run-off.. I what's the EC when you provide nutrients to the plants? How often do you feed the plants? The purple stems i don't think is an issue (usually purple means a P deficiency, but then it would involve the leaves, and not just the stems... it can also be genetics)

Bonjour, je pense que ton problème est l’excès de fertilisation.. on le voit parce que tes feuilles tombent et tes tiges sont de couleur violette . Mais quand les feuilles tombent c'est à cause de l’excès fertilisation, ou de l’excès arrosage, ou de l'excès de chaleur ou tout simplement que c'est la nuit et les feuilles tombent légèrement. Bonne culture ! 😊
