You are treating it like soil... you can't do this with coco
Do you have some EC & PH numbers?

I will check my ph when over the next day or so. I know it’s important but have been more into the yellowing...
Want to concentrate on switching over my light schedule to try reduce humidity during lights off & temps during lights on
Like I say buds are developing, I can notice every day (more so the lower ones)
18hr darkness today/tomorrow then another 18 following day seem the best option or keep lights off until 8pm tomorrow night ?

That's pretty much bang on mate!! Coco should be fed every day, sometimes even twice daily if they are hungry enough.
But they will tell you, don't just assume it. The best way to feed is, once they have a couple of sets of true leaves, start your seedlings at 0.2 above your background ec,(what it is from the tap) and then watch the plants!!!
As long as they maintain an even green colour, they are getting everything they need so leave everything where it is. If they go darker, back off the feed by 0.1, if they start to pale, increase by 0.2 but only if those leaves tell you to do so.
Start them off at 5.7 with every third feed 5.6, and once they have a few sets of leaves 5.8, again dropping the third feed to 5.6,(for calcium and magnesium) and once in bloom set to 6.0.
Key to success is accurate ph going in the pot and a good run off with every feed to set the ph in the medium.
Hope this helps mate.
Hope it’s just a deficiency. The third pic in my thread I have never seen a leaf like that before ?
This is only my 3rd grow now so I am learning slowly.
Last grow I was very anal about pH but not as much this time round sadly. Iv plucked the majority of the lower yellow leaves off and going to keep a eye on see if many more start turning yellow if so then I got a big problem ?
Anyone have a input about adjusting my light schedule? Need to get the RH down, I have just bought a 10L de humid Incase I need it but only growing 5 shouldn’t really be needed in summer, right? Also got a small one on 24/7 inside my tent which takes a while to fill
7” oscillating clip on fan blowing on each plant as it oscillates & a 5” extraction fan so airflow is pretty good, bit more negative air pressure than id like but at least it keeps smells at bay

You are growing in coco. Yes, flush them b/c of salt build up at lethal levels. BUT, as said, you need to feed. Coco is inert.
Give em a good blast at EC 0.4 (from base) ..... (if using tap water settled for 24 hrs - then 0.3 from base), PH 5.8 and go from there ...... Coco responds quick... read the leaves....if no change in 24 hours up feed to 0.4 (in tap) or 0.5 in coco EC, PH 5.8.
Keep upping slowly till the leaves are a light green
