Now plant pics

Picture above, not sure if lower fan got the fan leaf, but it looks rough.

Same leaf just better shot.

@Waira @IndicaIVoz these two should be able to help. I am right in the middle of somethin, if no one gets back to you by the time I am done I will see whats up with your plant and try to help if I can

More.

Tried to make this as detailed as possible. I have done some light trimming to lower sections, removed dead fan leaves and cleaned up behind it. I have been tending to it everyday, so just putting this out there.

I thought it was a nitrogen toxicity issue, from pumping too much calmag into it, however I am a little lost as to what's going on now. I am in flower at day 50 and as you can see, all tips are burnt, so, just kinda carrying on one day at a time.

Any thoughts?

That shit almost looks like fire blight but I dont think that is possible on cannabis

Boo'-- What are you growing in? I'd like to see whole plant pics too,... most important is the pH in that pot! That I really need... do you have means? I think you have a cumulative build-up of nute salts starting to show, which can jack the pH out of range, and interfere with other nutrient uptakes,... I see what might be some Ca defc. starting, but the yellowing and necrotic patches look like a mix of things,... tip burn, also a clue,... Might be time for a serious flush, best done with a flushing agent, like Sledgehammer, Clearex, etc.,... TJ, I see what you mean, and it's very unlikely indoors,.. but stressed/weakened leaves are more susceptible to microbial attack,... I don't think that's the case here, it's just tissue dying from toxicity issues,...

Can't believe I missed that.

Growing in biobizz light mix. Also I believe you may be right about salt build up, the bottle I used to feed with was getting a touch of white shade which I can only imagine what it's doing inside the Airport, as for reading pH, that's the last tool on my Amazon list that was getting ordered 2 days from now. ( I do have a standard pH kit but nothing fancy, it has solution for test and pH up and pH down.)

What is top recommendation for the flush agent? I can probably start with that? Or just hold off till pH has been read from the soil and or soil flush?

Full plant picture incoming momentarily.

Here they are as requested, many thanks for all input that has been given to me, in your debt so much already!!

Tried to cover every angle possible.
