Is this leaf septoria? Cal def?

Hey guys first grow ever and everything has been going good. I’m on day 49 of flower. Yesterday (day 48) I decided to start giving them pure water only No nutes to start the flush. I noticed a few thichomes amber, very few like 2% so I feel like I only have a few weeks left before harvest. Anyways, today I come look at the plants and they have these weird spots? These were not here yesterday at all. I gave them distilled water which is what I’ve been using. Humidity may of sat a little high in the tent last night maybe 55%? But it’s back down to 50 now and normally it’s at like 44% the main plant affected is a small plant in a tiny plastic pot so maybe it’s a root problem? The other plants don’t really have this showing on them. Just yellowing of the leaves but that’s been happening bc I kind of weened them off nutes

I would say the brown blotches on the leaves in pic 5, yes. But don't over react. Maybe add a little cal mag to the next watering. Don't spray her. Just let her finish up. your going to trim the ugly leaves off later anyway.
.Don't worry about the purple.

Yeah the blotch in pic 4-5 are mainly what im concerned on. Should I trim them off?

If they are a big problem for you giver, if not don't they won't hurt the plant. Just let her finish up.

Calcium. Have never seen septoria in a tent, only have a few years under my belt though. Septoria will have a lighter yellowish ring around the dark spot, whole leaf will lighten up mimicking a nitrogen deficiency. Cant miss it

I stopped cal mag probably 2.5 weeks ago because I had lockout so cal def makes a lot of sense but I don’t want to add any now bc at this point the plant is almost done I’m trying to flush.

Il just let her finish out as long as it’s not gonna harm my buds I don’t mind I’m ready for the plant to start looking wonky bc of the flush
