I grew these Dwarf Munstead Lavender plants from seeds and now they are 3 and half moths old. Room temperature is moderate between 15-20 degree celsius. I water when I see the soil is dry. I usually mist my plants & soil both with Neem oil & dish soap mixed in water once a week. They all are under grow light 12 hours a day.
I am trying to figure out what causes my lavender plants do wilting, I treat all of them equally but only 3-4 plants are doing well and others are not.
Top Lavender leaves are turning soft, silvery & then dies out completely. I already lost 8 lavender plants same way. Can anybody help me what should I do to save them?
I would appreciate a lot if someone can help me out.
Thank you very much for look into this.
