Thanks, yeah its old damage from when the soil ran out of stuff for the plants to grow.Fluffy colas, looking nice. Is that some yellowing on the tips of the leaves on the girls in the back? Is that from before or new?
I'm at about the same time frame as you. Ive recently started to up my nutes but I haven't seen any signs of stress yet so I'll give her a bit more next time. That will bring me up to 1/2 dose.
