My leaves have developed brown and yellow spots. My soil is ph is 6.5 so I have ordered some ph down which I will get on Monday. Am I correct in my assumption?
I have a fan going but I had overwatered them a bit so I'm letting them dry out a bit first and then onto 200ml every 24hrs. I did feed them about 2 weeks ago, if they don't improve over the weekend I'll flush them.
