Excess of nutrients, maybe one specific is building up in the soil

What could be causing this?
I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far. I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout. Anything else it could be??

Nitrogen deficiency??
Looking like I have a nitrogen deficiency. Thoughts and what do I do to correct other than what I've done already with a top dressing off earth worm castings and blood meal?

Yellow lower leaves on 8-9 week old plants - Deficiency or age of plant?
Lower leaves are starting to yellow on some of the plants. I think I have corrected my cal/mag issues but now these yellow leaves. Going into week 9 of flower. Is this normal because of the age of the mature plant or a deficiency? Or is it still cal/mag deficiency?

I can not take out of the tent to the darkness more than 4 at once and wanna hear your suggestions before I go with yellow sugar leaves or some amberish :D
I read something about harvesting immediately (not to crap the flower) when sugar leaves start to turn yellow and I have some! On the other hand, I saw some trusted videos that has some yellow sugar leaves. I want to ask you if you have any experience with this issue?

Age or Deficiency
I have noticed one of the girls fan leaves have all started turning yellow and drooping. It looks like they are turning from tip to stem and some of the smaller leaves have also started to turn. Is this due to age or a deficiency of some kind?

What's wrong with my seedling?
I don't understand why there is something strange in the leaves of this seedling. It happened to me for the first time, even though I was always raised in the same technique. As a fertilizer I just added 0.5 ml to 1 liter of biobizz grow.

General health
Advice please just on wether it's looking healthy. :) I've been too careful with watering and some leaves turned yellow. Feeding 1 litre every other day but maybe that's too little? Stopped with the Biobiz fish and switch to growbloom. Leaves at the top look droopy still?
