Soll ich sie spülen und neu düngen? Ich hab echt...

To me, these look like the symptoms of a plant that is growing in soil that is constantly too wet. 6.6 pH in soil is absolutely ok. No need to "flush", just get a proper wet/dry cycle happening and maybe increase your dosage of "grow" fertilizers slightly. The best way to water is to wet the entire pot until some water comes out the bottom of the pot and then to not water again until the top 3-5 cm of the soil are completely dry again. Never water to a schedule, like every second day "just because", waiting until the pot starts drying out is essential. You may have to change the lighting to 12/12 to initiate flowering, this plant may have missed the genes to make it flower automatically......nature can be weird and a bit random at times!

Hey there, I thing you have an nutrition block due to bad ph in your soil Your lady looks pretty pale because she can’t absorb any nitrogen and I took a Quick Look at your diary and noticed your stems are turning purple because she absorb phosphorus I would try to flush her a bit with water at the correct ph Almost all plant problems happen due to the following 3 possibilities 1. Bad ph in the root zone 2. To much to not enough water 3.to much or not enough nutrients She should rebound in a few days When she is rebounded you could try to force her to flower by changing the light cycle tot 12/12 and see if she starts flowering Happy growing ✌️
