Been feeding 10-10-2 bat guano (super grow) and now some 1-9-1 (super bloom) for 3 weeks, still getting brown dead spots on older fan leaves. Maybe still a phosphorous deficiency and plant taking awhile to intake the nutrients?

Nitrogen Toxicity?

Burn leaf
I’m seeing from last week this issue on some LSD-25 leaves, what could be causing this type of “burn”? Could be consequence of low temperatures during last week (11 Celsius degrees)

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)
I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static

Should I trim the bottom single leaves?
Hi GD peeps! Thank you so much for all the help and answers so far. You are all amazing <3 So I have a question regarding the bottom single leaves (the very first ones) should I be taking them off or trimming them? They don't get much light anymore due to the larger leaves.

Red Petioles
I've noticed that the petioles on many of the fan leaves have turned red. They're not showing any other signs of anything being wrong. Anyone have any info on this?

I've recently switched to 12/12 and because of the temps where I live I have opted for lights on 10pm to 10am, now just a quick question, during uninterrupted darkness would me briefly opening the tent to water badly disrupt this? Using my phone light to water the plants?
