I moved to a new house this week but had to leave my plants in the old house for almost a week..
I'll update tonight and show you what has happened...
I was back home to feed them water and nutrients 2 times and 1st time she looked so sad..
Checked her 6 hours later and she was a happy girl..
I think it's too late to worry now, but in the future you can try adding some calmag supplement will give her the magnesium and calcium you don't get in some water sources.
@Cnk671, i just saw your setup... I'm sure you'll do fine... My only advice is not to overthink and just let it grow... That's what I did... I don't have much equipment yet... Light, tent, nutrients and a loupe... Let her dry out a bit between waterings..
@Wicked_Stix, well I flushed it with 10 litres of water yesterday, maybe it lowered the pH... I'll try to feed again next watering and see if it moves..
Thank you so much for answering my question...
