Spotty leaves

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?

Ta,

Lar

looks like too much nukes. I would flush them ans cut way back

have you got good ventalation and a fan on the go. also plants looking a bit dry 200ml of water every 48 hours all the best

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.

Thanks for the help.
