Need help to diagnose a problem

[Beboo]

Hmm...I have also noticed from the lower branches that they are turning purple, which is an indicator of chronic over watering (which could have been from spraying them also)….which means you need to water/ feed them but leave a period for the soil to dry so the roots can look for the nutrients. how often are you watering/ feeding them...just curious...and that temp being 2?

Actually i used to give them water every day. But the nutrients only started to give yesterday
