Hi good people, i have some sativa girls which started showing up in good shape... but suddenly 2 of them started showing some bad symptoms in the last couple of days... they looked great before that... i plant them in the balcony and till now i didnt give them more than NPK... i give it once per week. first one looked like this 2 days ago and today she looked like this.... so she is deteriorating fast((( the other one was growing fine till today morning... in the afternoon i found those white lesions on a couple of leaves... im afraid that it will spread... please can anyone help me?
