That looks like you're scorching it with your light. How far down the plant does it go? Give me some of your grow details...

I am growing in coco loco with fox farm line including beastie bloomz right now along with bloombastic and terpinator. I have a mars hydro sp250 and plenty of air circulation. However, I can’t seem to keep the temp s below 84 which hasn’t seemed to be an issue till now.

Try raising your light a bit. Once you're in flower with these conditions, you're just going to be burning off terps and resin. If your can afford one, I would look into a temp controller that does separate day and night temps, a higher capacity extraction fan should help in conjunction with that.

Calcium and Mn deficiency, Mn/Ca are not mobile which means when you correct you wont see it in the already damaged leaves.
Probably with a P deficiency on the way
Any idea if you pH is correct?,
also if your plants for whatever reason are eating a lot of calcium or phosphorus efficent for whatever reason...foliar applications...pH range, large amount of nutients that readily available will deplete Mn, same is inverse large amounts of readily avialable Mn will make Ca and P more readily available

Early flower means more Ca, more intense light equals more photosythesis means more Ca is needed...same with P in flower
This means if you have a Mn deficiency it will show up with them, but as you correct you will only see P defiency get healthy again ...P as phosphate is mobile, your plant should convert avilable phosphorus into phosphate

Kinda looks locked out looking at it from your point of view, and the other plant was borderline N tox too.

Lock out isn't really a thing..a very very overused and misrepresented term,
Border line N tox? Looked a lot like heat stress

In my expierence , nute burn heat stress, almost any dying of the tips...all creat curl
N tox will be seen in older larger fan leaves first as they have the most N, and also not just one leap tip the entire leaf will curl hard

Looks like numerous issues , i only saw the first set of photos....
Second set shows some burn, cal deficency and looks like some heat issues
N toxicity will make your plants like crazy dark green, althought i have no idea your camera settings or lighting which will affect the white balance aka color represented

When multiple issues are present best to flush and recharge your media with feed.
What kind of nutrient/nutrient delivery system are you using

It is in coco if it's not treated right. You know CEC and what not.

Theirs no CEC in coco, it is an inert media no cation anion exchange..i guess charge was a bad term

They are 2 different strains and this is under regular white light! They are doing well but I don’t want these problems to get out of control! This is only my third set of plants to flower so I am still a newbie and trying to really get a handle on NPK and the whole thing confuses the crap out of me! I have yet to understand it completely! So should I be giving ANY N at this time?
Thank you all for your help!!!

I feed them once/twice daily. I am currently using big bloom, tiger bloom, beasty bloomz, terpinator, bloombastic, and I just recently started using cal mag again. (I didn’t think there was a need for it with tap water) Is this too much? I have backed off from 1600-1800 ppm to 900-1100 ppm and I’m very unsure. The peyote critical seemed to like the higher nutes and I am going to start feeding them separate since they are liking different strengths! Is there any way to explain the NPK for easy understanding...like how do I keep the ratios correct with so many different things?? Any help is GREATLY appreciated! I posted pics below.

There are hundreds of articles and studies to show coco has a high CEC, its not inert either. It naturally contains high levels of K which is slowly released.
